Bucky thinks that maybe Yelena had forgotten about their tentative plans when he doesn't hear from her for two weeks. It's fine though, since they hadn't made solid plans, and Steve got back from his mission the night before. Bucky was definitely otherwise occupied so it's a good thing she hadn't messaged. He's back home now though, not needing to be part of Steve's debriefing at headquarters.

He definitely remembers locking his door, so finding it unlocked is a little strange. He doesn't often get visitors, aside from Barton coming over to harass him and bring him pizza. He knows that Barton is also at the debriefing though, so he steps into his apartment with caution. Looking around, he spots her. Yelena is fast asleep on his couch. That explains the door.

Bucky drops his bag on the counter, making sure to not be too quiet. He's positive that she's clocked him being home already, and just written him off as a non-threat. He knows what it's like, sleeping lightly, just in case. But she knows that she's safe here, and if she doesn't want to wake up just yet, then who is he to force it on her.

She's been away for two weeks now doing who knows what, so if Yelena wants to sleep in a safe place, Bucky isn't about to stop her.

Instead, he puts his groceries away and settles into the chair to finish his book.
