[Klaus is used to being the one breaking down! Ben really... almost never freaks out, he's supposed to be the level-headed one. Like Klaus is supposed to keep it cool if even Ben can't??

But also, "stop breathing" is sort of the opposite of what Klaus meant. What he wanted to imply was "stop breathing incorrectly, my beloved brother," but far be it for Klaus to ever say something comprehensible.]

I— That's not what I meant! I mean... Do you... have to breathe? Are you just...

[He waves his hand around vaguely. Even he doesn't know what he's trying to ask right now.

But, okay. Obviously, we need to figure out more about all this. So Klaus just... takes a step forward, and grabs Ben's face with both hands.

He looks him over, partly because holy shit he can feel his brother's ??skin?? ghost skin?? Wow. And also partly because he's checking to see just how deep this goes, exactly.

Then he moves the back of his hand to Ben's forehead, feeling the temperature.]

Well. Good news: you don't have a fever. Bad news: I think you have blood, my man.
