There's still work to do. Still some shreds of a mission. Winter sets Yelena's hand down, opens his eyes, and starts patting her bloody clothes. Her tracker, he needs to find her tracker. He's not leaving it here. He might have to leave her, but he won't leave that little signal that will have her name on it in his phone.

Finally he fishes it out of a pocket and tucks it into one of his, and only then does he pick himself up, unsteadily. They need to finish whatever this is.
