[How about running into someone else you probably don't want to see right now? "Running into", or more like that happening entirely purposefully, as Bucky's mission when everything is back to normal... is to find those important to him, to talk with them, to make sure they're alright.
It would be stupid to assume Elsa isn't one of those.]
... hey. [One hand extended towards her, palm up, Bucky slows down his steps, looks at her with his eyes wide, imploring.] Please, Elsa... don't run.
