Winter scrambles over in the other two's wake, expression one of horror. "Yelena. No. No, you can't leave--" She can't leave him. She's been his person, his support, the only person who really understands him. He became a person for her. What will he do if she's not here anymore?

He fumbles for her other hand, clutching it close to his chest, wanting to wrap her up in his own arms but Kate already has her.
