[Steve just nods - he doesn't ask why or how Bucky knows that, he just assumes it's because Bucky's been here longer. Why else? He's probably seen people die, or known them, and this is just Steve's first time around the block, seeing it happen. He's trying to get used to the idea, and he will, with just a little time. He's gotten used to a lot, even just being here. And a lot more, back home. So this will be the same.

He does nod a little, though - he's talked to her over video, he saw it. He didn't ask. He didn't figure it was his place. And he'd always hated when people had given him that look, like they pitied him. Like they thought something was wrong with him. Bucky had always just looked at him and saw Steve Rogers. So he tries to do the same for others. She was just Cosima. Not an oxygen tank.

But even he knows it's not easy.] She probably appreciated that. Do you think she'd mind visitors? I mean, if she's up to it - I figured I might stop by. Just to see how she's doing. [He knows what it's like to be stuck in bed. He was thinking he could bring her something to do, if she'd be up to it. Maybe just talk.] Helena's fine though, right? I mean - she was never like that? [Then again, since they don't know why Cosima's sick, it could have nothing to do with being a clone.]
