Bucky knew that they hadn't really gotten to the real depths of what was going on here, and he didn't expect them to. She was on the verge of a breakdown and it was something he'd been anticipating for a while. This place, it could be a nice distraction from reality. He too was clinging to that, knowing what he knew of the future back home. Knowing he was going to go back and die soon after, knowing that even if he was brought back, she wouldn't be there. Ever. And Clint? He wouldn't even let himself mentally go there.
She'd been nonchalant about what happened, about her dying, when she first came because she felt it was the right thing to do. That was all well and good, but that didn't mean it was the right thing to do. And it didn't mean her loss was something to just get over and forget about. He guessed, it was reasonable to say that any of them -- especially the Avengers -- put their lives on the line countless times. Every time they suited up, it was with the risk of facing some perishable end. But that didn't mean it was just okay. Natasha deserved to be angry, upset, heartbroken over her fate. Why shouldn't she be?
Moving away from the Doors was a good idea. Bucky was all for it so when Clint suggested it and Natasha agreed, he stood up beside her. "Your place?" He suggested, referring to Clint's, because that nest was probably the best place for this. He still had the goat at his own house and while he'd built him a pen he still was kind of a dick and tried to come inside a lot. Bucky wasn't sure how far they'd get with her tonight. This felt like a work in progress situation and that was fine. She was going through an onslaught of emotions that she should've been feeling probably the entire time she'd been in town.
