What are you doing?

Prompt: You and Yelena are sisters. When news came to light that Clint Barton was responsible for the death of your other sibling, Natasha Romanoff, you and Yelena went on the hunt to kill him. But, you're soon encounter with someone who wasn't supposed to be in the picture. Your girlfriend, Kate Bishop.

You and your sister ran down the roof of the sky deck, skimming over the AC coolers that were spread around. Clint was far at front, trying to escape. Earlier, Yelena had shot him on the leg, so both of you knew he wasn't going to last much with his sprinting.

As the two of you continued running behind the limping man, he shot multiple arrows towards you, but you managed to dodged them. It didn't took long, until you caught up to him, and pushed him to the ground.

" Good job, sister," Yelena impressed, congratulated you. Her Russian accent flowing out of her lips, as she cursed the man you had ceased on the ground. " Now, you stay there, dear Barton," she stated, pointing her gun at him.

Before she could trigger the gun, you looked up when you heard your sister scream in pain. An arrow as ran past you and towards Yelena's arm. You immediately whipped your head to the location the arrow came from, but  Clint took your distraction as an advantage, and pushed you off of him. He quickly stood up and left running.

" Please stop," the girl who shot your sister came into view, revealing herself. Your back was facing her, but you knew exactly who she was just by hearing her voice. It was Kate. Your girlfriend.

" Oh, this is great," Yelena took her mask off, knowing were this was going. " This is absolutely, great, Y/N!," she shook her head, pulling the arrow she had stuck on her arm with a sharp gasp.

As you turned around, you were right. A nervous Kate was pointing an arrow at you, ready to trigger it. Kate still didn't know it was you, but by seeing Yelena, and her mentioning you, she suspected.

" Kate, what are you doing here?," You spoke softly, pulling your mask off and revealing yourself.

" Y/N! Oh my god..," she lowered her bow, running down to you.

" Kate, you're not supposed to be here," You warned her, as she hugged you.

She then pulled away and looked at you with her eyes widened, " I could've killed you,Y/N!"

" Nope, she could've killed YOU, princess," Yelena added annoyed, and then took a glimpse at you. " I'll leave you two in peace, I got a man to chase," she added and then stop once she realized what she just said. " I don't chase men, I chase women. I like woman. I'm going to chase Clint Barton. I need to kill him," she immediately corrected herself. " I'll see you later, sister," Yelena dropped a gadget down on the floor in which converted into a cord. She quickly attached it around her waist, before waving a goodbye at the two of you, and disappearing on plain sight down the building.

" What?! No, Y/N!, she can't kill Clint!," Kate immediately shook her head, looking at you nervously. " Are you trying to kill him too?"

" Kate, babe, Clint killed our sister," You sighed, scratching your forehead. " We were going to kill him, but then you appeared and he got away. Kate, why did you help him? Why are you here?," You arched an eyebrow, confused.

" He didn't kill your sister, I promise. Y/N, you guys got the wrong person. I know Clint. He loved Natasha. Please, Y/N, we have to stop your sister!," Kate anxiously explained, but you shook your head.

" Kate, I'm sorry. But you're the one who doesn't know him," You stated. " Please, just go home. I need to finish what I started. "

A/N: Yelena and Kate = perfection.
