Sometimes, there just wasn't anything to be done in a given moment. And that kind of seemed to be what this was. Bucky knew that not everything was fixable; not right away, at least. This had been a long time coming, and now they were finally at that point and he couldn't do anything except be present with her. And maybe that could be enough for right now. She wasn't alone. She didn't have to ever be alone if she didn't want to be. That was kind of how it'd been when she and Clint showed up at his house. They couldn't change what had happened, they couldn't make him really feel any different, but Bucky had found some comfort just in knowing they were there. They were two people who gave a shit. And that went further than most would think for someone like him.
Of course, he wished he could do more. If Bucky could take all the negative feelings she had and carry them for her, of course he would. Or if he could rid them from her all together, then he'd do it without hesitation. But that wasn't how the world worked, and he of all people knew that. Burdens were burdens, and some of them had more than others to carry. The three of them all had their fair share. But they also could help carry them together. That was something he was beginning to learn and accept, even though he wasn't that great at sharing just yet.
"You say that, and if it's true then that's great," Bucky said. "But that doesn't mean we're just going to walk away, Natalia. You can't get rid of us that easily. If you're fine, then all the more reason we should all go crash at Clint's."
