A/N: So we're finally here. After 4 years, we're done. Sorry for the long wait. Thank you for riding with me through this very very long journey. As always enjoy.

Everyone watched the spaceships fired their weapons to the Earth with breath held tightly and fear gripping in hearts. When it cleared and the Earth was still whole, everyone cheered. Then, Stiles' barrier glowed bright white and a beam of pure white light shot up the sky. It shattered the ships' shield, some were even destroyed.

But Steve was afraid, because he knew this light, he knew this power. When the white light receded, their bond that was singing loud and clear earlier was beginning to get quite and dull.

"No." Steve whispered fearfully. He called out to Stiles but there was no answer. He couldn't feel what Stiles was feeling. He fell onto his knees. He was losing Stiles and He didn't know how to stop it.

Then he felt it. He felt the second Stiles' heart stopped and their bond became but a silent string. Someone called his name but he can't focus on it. He couldn't focus on anything but the ringing silence of his soul. He couldn't feel Stiles anymore. He didn't know what to do. The Earth stood whole but he was breaking apart.

Someone touched his shoulder and knelt in front of him asking if he was okay. He looked up to see Natasha looking at him worriedly. His vision became burry.

"Stiles." He whispered the name sorrowfully and felt tears running down his cheeks.

Natasha understood and her fear for the boy became evident. "Somebody check on Agent Stilinski!" She ordered. She turned back to him and cupped his face. "Steve. It's gonna be okay. We'll save him."

Steve shook his head because he knew Stiles was gone. He knew it before someone told them that Jackson was giving him a CPR and the medics were on their way. He knew that Stiles heart wasn't beating anymore.

He asked him to do the impossible and it took everything he had. This was his fault. He knew Stiles couldn't do it anymore but he asked anyway because they needed a miracle and Stiles would do anything for the people he loved. Steve would give anything for even just a chance to save the man he loved, to let his heart beat for both of them.

Then Steve remembered he died too. He was brought back from dead and Stiles gave him his heart. Stiles wasn't completely gone. He had a piece of Stiles inside him. A glimmer of hope bloomed inside his chest. They had a connection. He could do the same. He could still save Stiles. He couldn't let him go without a fight. Not yet. Not ever.

Steve forced himself to pull himself together. He needed just one shot, just one heartbeat, and he would never let go.

Steve called his lifeforce, called for it in every fiber of his being, down to his very soul. He begun to glow. He grasped at the lifeless string of their bond and let his lifeforce surge through it like fire. But something stopped him from reaching Stiles, a wall he couldn't push nor break no matter how much he pushed.

He couldn't give up. Stiles didn't give up on him. He had no right to do any less. He recalled all the times they spent together. He recalled the way Stiles made him feel. How he looked forward to the times they could be together. And he pushed all the into their bond. He needed to let him know how much he loved him and how he would always love him.

The wall shattered and Steve pulled as hard as he could. Their bond blazed like fire and he could feel Stiles again. It was faint and faded. When he called for him, he didn't answer. But he was there.

"Steve?" Natasha called him.

He looked around and everybody was looking at him. Agent Coulson was kneeling beside him with tears running down his eyes. "His heart is beating again." The man said with a smile.

Steve sighed in relief. Because that is hope. And that was all he could do.

Steve took a deep shaky breath and stood up. "We need to wrap this up. Don't let any of the ships escape."

But as he said those words, the ships were falling off the sky. They were making one last attempt to destroy the Earth. It left them no choice but to destroy them.

"This was all your fault!" Jackson threw Steve into a wall and cracked it. Steve let him punch him, he took it all. The anger, the sadness, the guilt. He didn't even try to defend himself because he knew. He knew that Stiles would do everything he asked him to. The kid trusted him. Stiles would follow him at the end of the line. No, it was not just trust. He knows. That the sarcastic, klutzy kid loved him. So much so that Stiles brought him back from the dead.

"I'm sorry." Steve said, his voice raw with emotion.

"YOU BETTER BE!" Jackson bellowed angrily. Jackson could hear how utterly destroyed Steve was and his anger crumpled down. All that was left was the fear and worry for his friend. He just broke down crying on Steve's chest. Jackson hugged him and cried his heart out. Steve hugged him tight and let both of them ride through their emotion. Both of them felt Stiles' passing far too deeply. Even if it was temporary, it shook them down to the core. You couldn't lose someone who touched your soul without losing yours.

When both of them calmed down, they joined the others outside Stiles' room where Simmons was saying Stiles condition. Stiles lost a lot of blood and entered coma. There was also a big damage on Stiles' heart she couldn't explain how or why he had those. Steve knew why and he clenched his fist in anger with himself.

Steve felt something watery on his hand. He looked down and saw blue fire looking at his fist. It was a wisp. He couldn't be mistaken. It looked like how Stiles described it. Out of curiosity he opened his hand. There was blood on it. He realized it was Stiles blood that he got from Jackson.

Then there was a cellphone ringing.

"It's Stiles' dad. What do we do?" Jackson said.

Steve looked at Stiles and there was a wisp floating above his head. Steve wondered why they were here. He looked back down at his hand and it was still there. He lifted his hand closer to his eyes and the wisp floated up with it. It was swaying its arm from his blood to Stiles' direction. Steve got what they were saying.

"Tony have JARVIS intercept the call. Tell Stiles' dad that he forgot his phone during the evacuation and he's fine."

"But Steve-" Tony complained.

"Trust me." Steve said then he turned to Jemma. "Use my blood for the transfusion."

Everyone got silent. "Captain Rogers, are you sure?" Jemma asked.

"I am." Steve said without hesitation.

Jemma's eyes widened in surprise and she looked around but everyone was as speechless as she was. "But we have to do some test first. We don't know what serum will do to Stiles-" Jemma was getting anxious with this.

"It will work." Steve said boarding no other option because it had to work. "The ritual drained all of Stiles lifeforce. That's why he can't wake up. That's why I can't fully reach him. I can't pull him back to a body that can't house a soul."

Everybody looked at him with confused expression.

"What are you saying, Steve? You're not magic. How can you 'reach' Stiles?" Tony asked.

"We have a connection. A bond." Steve looked at Stiles and realized something with wonder. His hand came up and rest on his chest, right where his heart was beating fast. "He's my soulmate."

"But Cap, we don't know if the serum will help Stiles recover or make things worse. There's just too many variables that we don't know. I cannot in good conscience do this without knowing what will happen to my patient." Jemma said sternly as she could while facing one of her heroes.

Steve understood her reluctance. This was a crazy idea. But he had a feeling that this was the only way to save Stiles. He had to convince them.

"I died." Steve said. "That day when I fought Doom in his ship, he put a hole in my chest. Got no pulse because I got no heart." Everyone stared at him like they were seeing a ghost. "But Stiles never gave up on me. He brought me back from the dead. He used his own lifeforce to heal me. If I give it back to him, if I share my own, maybe.... just maybe it'll be enough to bring him back." Steve moved closer to Jemma and he took her hand. "Please, Ms. Simmons, help me save Stiles."

Jemma stared hard at him and Steve could see her mind racing and battle her indecisions. "Okay. But I need to run some test first just to make sure it safe."

Steve nodded and gave her a small smile. "Thank you.

Tony and Bruce helped her with the test while Jarvis answered Stiles' dad.

"Do you know how much hold you have on Stiles? He's ready to jump before you even give the word." Natasha told Steve.

They stood at a corner of the room watching Simmons do the blood transfusion. The test had been all positive and it shocked everyone just how perfectly compatible Steve's blood was with Stiles.

"I know." Steve said, finally acknowledging the amount of faith and trust the younger man had bet on him.

"But he's not aware of the hold he has on you." Natasha claimed knowingly. Steve clenched his fist. He hadn't even told Stiles what he felt for him.

Natasha touched his tense arms. "But the truth of the matter is it's never about your authority or saving the world. He knows it. You know it." Steve glanced at the red head. The thing she was implying was obvious but he and Stiles had never really talked about it. "What you and Stiles have is something especial. Don't let this stop you from taking it. Someone of us can only dream of having what you two have."

Steve nodded. "I will never leave him."

Natasha smiled at that. She gave his arm a reassuring squeeze before she removed her hand.

When Steve looked back at Stiles, he remembered this happening before. He had seen Stiles in a coma... but it was because of different reason. Something about a sleeping spell and a car accident.

Steve blinked in confusion. He didn't know what just happened or where those memories came from. But he knew, deep in his bones, they were his and they were real. His heart ached, nostalgic for something he did not quite understand. And at the same time his heart longed for a feeling whenever he kissed Stiles.

Steve sighed heavily. Stiles, you need to wake up.

Steve had not left Stiles ever since he got there and his werewolf companion had made camp in the room as well. On the clock, Clint would coax the werewolf out for a quick shower or to eat food. The first time it happened, the werewolf growled at the archer and flat out said 'No'.

"I'll watch Stiles." Steve said. The werewolf snapped his glowing electric eyes at him, judging, challenging.

"Don't leave him alone until I get back." Jackson said, a lingering threat left unsaid.

"I won't." Steve vowed. That seemed to be the right thing to say. Jackson stood up and left the room with Clint.

Phil had visited as often as he could. It was hard watching the agent watching over his nephew. They didn't talk about Stiles' selfless move. It would be hypocritical of them to point fingers. And always before he left, he would give Steve a reassuring pat on the back.

On the second day, Dr. Strange came in to check on New York because of Stiles' barrier. It hadn't gone down and the ley line powering it was still awake. They tried closing it but nobody could. It was a deadman's spell. It would need another life to break it.

Steve asked the Sorcerer Supreme to check Stiles via magical means. But that was a bust too. Stiles' presence was there but he couldn't pinpoint where. And when he tried summoning him from the death's realm, he wasn't there as well. The sorcerer glanced curiously at Steve.

"How about the Time Stone?" Jackson asked desperately.

Dr. Strange shook his head. "He's immune to it. His physical recovery looks promising and his lifeforce is recovering fast as well. If anything can wake him up, it's you two." He looked at Steve and Jackson. "If my guess is right, he's somewhere in the flow of magic itself. You have a bond that can reach that plane of existence. You just have to keep calling him."

The next day, Steve was the only left with Stiles. He couldn't bring himself to leave the younger man and nobody questioned it.

Steve sat on the chair besides Stiles. The silent and motionless form of the younger man was eerily hunting to behold. Stiles was always on the move, twitchy little twerp as what Clint said. A voice you couldn't silent. A storm in a little tea cup. A deafening laughter in his lonely hour. Something in his chest clenched painfully.

Steve reached out to touch Stiles hands. Cool and placid. Unresponsive to his touch. Steve wanted him to move. To do those klutzy jerks of his hands. Oh what he'd give for just a twitch. Steve brought his Stiles' hand to his cheek as he looked at his face. Something heavy pressed on his chest.

"Come back Stiles. You have to come back... I need you." Steve said, his voice was quivering. He pressed Stiles' hand on his cheek. Steve plucked at their bond, letting his emotions flow freely. There was no point of holding back. Wherever Stiles was, he needed to let him know he was waiting for him. He closed his eyes and kissed Stiles' hand.

Something buzzed in their bond. A short quiver. Steve held his breath.

"Steve?" A raspy voice called.

Steve slowly turned... And tired whiskey brown eyes were staring back at him.

Steve immediately stood up. Shakily, he reached out to touch Stiles' face. When his palm touched Stiles' cheek, Stiles blinked slowly. Steve released a happy relieved sigh.

"You're awake..." Steve said, breathlessly.

"I'm alive?" Stiles asked, hoarsely. His voice cracked from several days of no use. Steve nodded as tears fell from his eyes.

"I thought I lost you." Steve whispered. "And I didn't even tell you how I feel."

Stiles smiled and brushed away Steve's tears. "I know. I've always known."

"I tried controlling it, pushing it back. But... I've fallen in love with you." Steve admitted.

Stiles chocked back a cry of happiness. "I love you too, Steve." Stiles pulled him down and kissed him.

Steve felt something break inside of him, like the moment when you touched a balloon with a needle just before it explodes. Then the memories came rushing like a dam bursting. The date in Disneyland.... Stiles shielding him from Doom... The night at the pub... The kiss on inside the Ferris wheel... he waking up from a nightmare and seeing Stiles worried face... That lingering kiss as they disintegrated into glittering green lights...

Steve laughed into their kiss. Because dear Fates, he remembered it all. His heart rejoiced with pain and sorrow and his soul cried with joy and happiness. And their bond blazed around them and entangled them together in an unravelable heap of strings. Both of them gasped. Because finally, they found each other.

Stiles pulled him down into a deeper kiss and Steve went down eagerly until they needed to catch their breath.

Steve brushed the soft, pale skin of his cheek with his thumb. Stiles touched Steve's arm. "Took you long enough." The boy teased weakly.

"Better late than never." Steve said, smiling hopefully. "We have a lot to talk about."

"Yeah, a lot." Stiles chuckled. But then, he coughed from the dryness of his throat.

"I'll get someone to check you." Steve said. Stiles nodded despite not feeling that bad.

Steve got up and went to the door. He didn't leave the room instead he called an agent to get Simmons. Then he helped Stiles to some water.

Jemma came in with Fitz and begun checking him. Meanwhile Steve called Jackson and Phil then he informed the rest of the team.

"Wow, this is truly amazing. No immediate neurological and psychological side effects." Jemma said.

"Side effects?" Stiles asked.

"Uhm." Jemma cringed at her slip. She tuned to look at Steve.

"Steve?" Stiles asked. The older man walked back to his side.

"The ritual took a tall toll on your body." Stiles nodded. He knew just how much it cost to gain the power of the Earth. They've made the same bargain before. "Even with our bond, I can't pull you back completely."

"As it should be. The ritual demanded highly. It should be almost impossible to bring me back to life." Stiles said calculatingly.

"I know. I felt it. It took everything from you. You lost a lot of blood and your heart was burnt out." Steve said a little choked up. Stiles teared up the at the overwhelming emotions from Steve.

Stiles took his hand and brushed it comfortingly. "I'm sorry."

Steve shook his head. "Don't be. What you did is one of the bravest thing I know. You shouldn't apologize for it. We made a promise to be there till the end of the line."

"But still I'm sorry for what I've put you through. I've hurt you. There's no way around it." Stiles said.

"I know. But I'll never hold you to that." Steve said sincerely.

Stiles smiled at that and he find himself falling in love all over again. "I don't know what I did to deserve you." Stiles mused.

Steve snorted. "We both know exactly what."

Stiles grinned. "So... what did you do to bring me back?"

"Remember you used your life force to bring me back. I just thought maybe if could give it back to you, it might be enough to bring you back. So we used my blood for your blood transfusion." Steve answered. Stiles nodded because it kind of makes sense. Without Stiles, Steve couldn't use magic.

"Which brings us back to the side effects." Jemma interjected. She pulled down a hologram showing data of his body. "From what we observed, your body readily accepted the blood transfusion and Steve's cells had repaired all of the damage in your heart. But it did more than that, it begun bonding with the rest of your body as well. So we looked out for possible ill effects it may incurred on you. But from what I we are seeing right now, there's no signs of rejection. In fact, it had stabilized your brain chemistry and strengthened your body to almost perfect condition."

Stiles mashed through the information. "So you're saying I'm cured of my ADHD?" Jemma nodded. "Am I a super soldier now?" Stiles asked incredulously because that was both exciting and terrifying.

"That remains to be seen. Right now, the super soldier serum is focused mainly on repairing your body. We have yet to find out if it'll be consumed to the point that it'll fade away or replicate itself and stay in your system."

"Oh wow. It's just a possibility but this is both exciting and terrifying." Stiles said.

"Stiles are you okay with this?" Steve asked.

"I am. It's just a bit overwhelming to think about. What will tell Dad-" Stiles remembered his dad like he was punched in the gut. He must have seen the attack or heard about it by now. "My dad. What did you tell him?" Stiles asked.

"Stiles, relax." Steve said, putting a comforting hand on his chest to get him to lie back on the bed. "I've made Jarvis cover for you."

Stiles nodded and relaxed. "We're lucky you brought me back."

"I had faith that you'll be back." Steve said and took Stiles hand in his.

"So when can I go home?" Stiles asked.

"I'd like to keep you in for just one more day and run a few more tests just to make sure you are alright." Jemma said.

Stiles grumbled an okay because no matter what hospital he was, he hated being there, especially if he was the patient. Jemma and Simmons left with a promise to come back later.

After a few minutes, the door burst open and Jackson came jumping into his bed and embracing him desperately. The werewolf burrow on the nook of his neck and his hand rest over his heart. Stiles could feel the huge sob vibrating on his chest. Stiles enveloped his arms around the werewolf and draw him closer.

"I'm here now, Jackson. I'm sorry for what I've put you through." Stiles said.

"Your heart stopped. I couldn't feel you." Jackson cried.

Guilt rise up like a bile on his throat. Stiles nuzzled his cheek on Jackson's head.

"I'm sorry, Jackson. I didn't have a choice." Stiles tried placating him but it didn't change the fact that he did die and left him. And that must have been terrifying. He felt Jackson held on to him tighter.

"You're such an asshole, Stilinski." Jackson said with no heat.

"I know. I'm sorry." Stiles said softly. Jackson took calming shuddering breath before he pulled back and brush his tears with the back of his hand. God, he messed up this time. He needed to do what he did but that didn't excuse him from the consequences of his actions. "I- Jackson... You know what I did.... It might not be the last time..."

"No." Jackson growled. "You're not going to push me away. You're my pack. There's nothing you can say that will me make me leave you. I've known you for too long, Stiles. This bullshit will not fly with me."

Stiles smirked sadly. "This isn't good for you, Jackson."

"And so what? Not everything will be. You said it yourself. We're already in too deep this shit. And I rather spend my days with the people I cared about than trying to be safe and doing nothing. You're more than just my pack, Stiles. You've become the brother I never had. I can't abandon you just because shit hits the fan." Jackson touched Stiles shoulder. "That's not how it works. You've taught me that."

Jackson meant every word of it and Stiles couldn't help but be touched and proud.

"Look at you, buddy. Being wise and caring." Stiles joked with watery eyes.

"Shut up, Stilinski." Jackson grumbled with no heat.

Stiles saw Clint standing beside Steve. The archer came closer to him and ruffled his hair when he was close enough. "You gave everyone quite a scare kid. How are you feeling?" He said.

"Not as bad as I thought it'd be. Though I'm really hungry. Can someone get me some curly fries?"

"I'll get you a bucket full." The archer said.

A few hours after, the Avengers came to visit him. Thor gave him a proud pat in the back. Tony made sure he was comfortable with all the government funded facility. Bruce rechecked his conditions and Stiles urged the doctor to say it was good to go home which was met with a flat stare. Hey, he just wanted to go home. Daisy and Agent Ward also dropped by with some fruits.

When his uncle came in though, it was a punch in the gut. He looked so relieved seeing him well and alive. And when he embraced Stiles, they let their walls down and just let the relief wash over them.

"You gave me quite a scare, kid." Phil said.

"I'm sorry, uncle." Stiles said.

"Don't be, Stiles. You did what you have to do. It just.... It hit home." Phil said, barely keeping his voice intact. Phil kissed his forehead and ruffled his head.

Then Thor and Clint came in with food and drinks. Stiles felt his stomach rumbled impatiently. Everyone cheered.

Food was passed around. Tony hacked the intercom to play some music. There was pleasant conversation in the air. Even if they were in a crammed medical facility, everybody was happy and satisfied and having a bit of a good time. Stiles couldn't help the warm feeling spreading in his chest.

Steve sat back down beside him and offered him a drink and plateful of curly fries. Stiles grinned widely.

"Oh you really do love." Stiles said and picking a handful of fries and start shoving it in his mouth. He didn't orgasm. But it was close.

Steve looked unbelievably at him. "After everything that had happened, this convinced you that I do love you?"

Stiles shrugged. "The way to a man's heart is through his stomach?"

Steve chuckled and just shook his head. "God knows why I love you but I do." Steve said fondly.

                EPILOGUE

Before Stiles was discharged, they were gathered for a briefing. Deputy Fury and Maria Hill were standing at the foot of his bed waiting for the explanation he promised.

Stiles took a deep breath and begun explain how he and Steve created a time loop to stop the end of the world. About the sky bleeding red and another Earth in collision with their own. They explained the Incursion, how the universe was dying and that the Earths were the ones linking universes into a collision that will result to the annihilation of both universes.

The Cable, the group they just fought, were sentries from another universe sent to destroy the Earths. Apparently if you destroy the Earth, it would severe the link and stop the collision and thereby saving the Earth.

But that was not the end of it. Not when a group surviving the Cabal's attack fell into their own universe. They told Stiles that it did stop the incursion after their Earth was destroyed. But something else destroyed their universe after.

They had a plan. It was a long shot. But still a plan. It was better than waiting for the end of their days. They contacted the universe that they are in collision with. They agreed with the plan. They plan on data mining the time loop to know exactly why the incursion was happening. The changed how the time loop worked so that instead of the time reverting back, it was moving everything forward instead. Meanwhile, the other universe was moving normally and could start researching on how to stop it. Steve and Stiles had to forget everything to not contaminate the data. They would only remember when the sky bleed red again and the world was ending. Because that was the only time they could talk with the other Earth. And if they didn't have any answers, they would continue back into the time loop. And there wasn't any answer still.

It was a hard pill to swallow and downright hard to believe. But they wouldn't lose hope. Steve took Stiles hand in his and gave the younger man a determined nod. Stiles thought to himself, he would never lose hope. For his friends. His dad. Stiles tightened his grip on Steve's hand and nod back at him. Everything would be okay as long as they had each other.

P.S.; If anyone is a little confused, this was based on hickman's "Incursion" and "Time Runs Out" story line. It's a marvel comics story about the end of the multiverse.

If you have any questions, feel free to ask.
