Bucky comes back to the tower after completing his mission, the others greet him when he walks into the living room, he looks around for you, but doesn’t see you, he asks where you are. Tony: "Oh, in your guys’ room, been there for about a week." Bucky’s eyes widen and he drops his bag. Bucky: "A week! Did you even think to check on-" He doesn’t finish his sentence, bolting for the room, leaving the other avengers confused and worried.
