Klaus is pretty sure he's hallucinating when he sees Luther's too-big form hunkered down at the bar like that's somehow going to make him blend in. He stands there and just stares for a minute.

He is absolutely not high enough for this. Of all of them, he expected Diego. Or maybe Five, because Five had apparently like murdered a bunch of people or something? Luther isn't Klaus's favourite person, but he's not the worst of them at all. Who did the deciding here? Okay, Lucifer, but what were the criteria?

He takes a breath and slides into the next seat just in time to see Luther take a drink of who knows what.

"Man, didn't you learn not to take things you don't know anything about?" Klaus asks, affecting a judgmental air as if he has any room to talk.
