"And my parents? Would killing them save you as well?" Cassidy asked, the exhaustion clear in her voice.

She was tired. The events of the night and her conversation with Rose was taking its toll on her. All she wanted right now was her parents and her bed.

But she needed to know. If she didn't get answers from Rose tonight, she would wonder for the rest of her life what had been the motives behind Rose's actions. And that was no way to live a life. Hell she wasn't even sure how she was supposed to go on with her life right now.

Even though she hated every single minute of it, Cassidy needed to know. Rose had to answer for everything she had done.

"They needed to die," Rose answered, her voice hard.

"Because they didn't adopt you?"

"Yes."

"That's not a good enough reason to kill an entire family," Cassidy shouted at her, unable to control her emotions.

"Of course you're on their side," Rose sneered.

"This isn't about sides. You were about to kill an innocent couple because they didn't adopt you. How can you possibly think that that is a good enough reason to kill someone?"

Cassidy's fear was momentarily replaced by her anger. She couldn't help her outburst. Seeing Rose sit here and justify her actions was making Cassidy's blood boil with fury.

"Because of them I had to go back to another man who thought I was a punching bag," Rose screamed.

"That wasn't their fault!" Cassidy shouted back at her.

"Yes it was!" Rose screamed.

She pulled at her handcuffs making the chains rattle against the table. Cassidy paused for a second before she realized there was no way Rose could get lose.

"You're blaming them for something they had no control over. How were they to know what kind of couple would adopt you? Surely you can see that there was nothing they could have done," Cassidy tried to explain, calming her voice.

But the fury in Rose's eyes didn't dissipate. Cassidy was slowly realizing that it didn't matter what she said – Rose wasn't going to let go of her anger.

To her, she was right. And that train of thought is what she used to justify her crimes.

"Why kill the other people then?" Cassidy asked suddenly, going for a confession.

A hint of confusion entered Rose's eyes.

"The other families that you killed. Why kill them? Martha and Leon left you there, so I understand why you want them dead. What about the other families? What did they ever do to you?"

Cassidy expected more anger, but instead Rose laughed. Again her mood switched instantly.

"Is that what you're curious about? Why I killed the other families?"

Cassidy nodded, not trusting herself to speak.

"I don't have a reason," Rose answered with a broad smile.

"What do you mean you don't have a reason?"

"I told you back at the house. I did it because it was fun. Seeing the blood draining out of someone. Watching the knife plunge in and come out filled with red."

Rose's eyes gleamed as she talked. She really did enjoy it. Even just talking about it, it was clear she liked it. The tone of her voice, the expression on her face – it was one of joy.

"Why families? You were so specific, boy then girl and all on the same date."

"I told you. The girls in the prison told me it's more fun when you have a pattern. One of the girls told me about how she led the police by their balls for a year. They weren't able to catch her at all. She taught me all of her tricks."

"Tricks to be a serial killer?"

"To be famous. I wanted everyone to know about me. To know that I was capable of killing anyone that I wanted."

"But why those families?"

Rose shrugged.

"I chose them at random mostly. I went to the park one day and looked around. Chose a family and followed them for some time. Following them and watching the perfect lives that they lived made me hate them more. It made it all the more fun when I killed them. When I watched them beg for their children's life," Rose said smiling.

Cassidy stood up shakily. She couldn't listen to this.

"Are you terrified little sister?" Rose teased.

Cassidy glanced at Rose and took in the big smile on her face. Rose was enjoying talking about this. It thrilled her.

Cassidy took a step back. She had to get away. There was no way she could stay here and continue listening to the nonsense that Rose was saying. She didn't spare Rose another glance as she bolted out of the interrogation room.

She didn't make it far out the door, collapsing against the wall directly opposite. That was where Wyatt found her when he came to her side a minute later.

"Cassidy. Are you okay?" he asked concerned.

She shook her head.

Being okay was not something she thought she would ever be again.

"I know it's a lot to take in," he stated.

That's an understatement.

She slid down the wall, her legs giving up. Wyatt sat next to her on the floor.

"I'm sorry that we're making you go through this," he apologized.

She shook her head.

"I knew that was what you guys wanted to hear. I just...I didn't realize what hearing it would feel like," she told him honestly.

Nothing could have prepared her for the array of emotions that were running through her at listening to her sister confess to murder.

"I can go in there with you if you want," Wyatt suggested.

Cassidy looked up at him.

"Would you?"

"There's some questions I have for Rose as well."

"Questions I haven't already asked?"

"There's some stuff from tonight that I need to clarify."

"Can't you just go in there alone?" Cassidy questioned, not wanting to go back in.

"I can. But Rose will react better if you're there. It's almost like she wants you to know about everything. She wants to tell you about the horrible things she did."

"But why? Why tell me?"

Wyatt shrugged.

"We're going to need her to answer that."

Cassidy looked down at her hands that she was wringing on her lap. Was she able to go back into that room and listen to the things Rose was saying? Could she do that? At this moment, she didn't think she could. But she couldn't deny that there were still so many mysteries. So many things that Rose did that the police wanted answers for.

She took another minute before she turned to Wyatt.

"I'm ready to go back in."

He nodded and stood. He helped her up to her feet and they walked into the interrogation room together.

Rose smiled brightly when she saw them enter.

"I knew you'd be back, but I didn't think you would bring your boyfriend with you," she teased.

Cassidy walked to the back of the chair but didn't sit. She couldn't stay still at the moment.

"I have a few questions for you," Wyatt told Rose.

Rose turned her gaze to him, and her smile turned menacing.

"Isn't their rule about fraternizing with victims?" Rose goaded Wyatt.

Wyatt ignored her.

"We found pictures of a family in your hotel room. Someone tried to break into their house tonight. He said a woman paid him to do it. The description we got from him matches you."

Rose grinned.

"I knew you were on my tail. I wanted you to think I was going after another family, but it had always been Cassidy I was after. I needed you distracted."

"How'd you know we'd find your hotel room?"

"I made sure you found it," Rose laughed.

"You were the anonymous tipper," Wyatt said softly, as though coming to a realization.

Rose tipped her invisible hat.

Sounded like Rose had played the police as well. She knew exactly what she was doing.

"Why confess?" Wyatt asked her suddenly. "You know we don't have any evidence tying those murders to you. Why confess?"

Cassidy turned to Rose. That was a valid question. She knew the only reason that they had been so adamant on her questioning Rose was because they had no evidence. If Rose didn't confess, they would have nothing on her.

Rose looked at Cassidy as she answered.

"I wanted her to know."

"Why?" Cassidy asked softly.

"Because I wanted you to know where it all started. There's still one important question you haven't asked me."

Confusion filled Cassidy.

"What question?"

"Who were my first victims?"

Her first victims? Cassidy had never thought about it honestly.

"Why would I care who your first victims were?"

"Because you were there that night," Rose answered smiling. "You were there when I killed someone for the first time."
