Klaus doesn't know much about whatever version of himself Diego had been hanging out with. Some alternate version who picks fights with the only sibling who's consistently given him second chances. And that gets it going in his brain - if that hadn't been this Diego's Klaus, then how is he to know who the siblings he'd grown up with were, compared to these alternates...and that thought hurts his head and his heart so he shoves it down to be examined later when he's alone...or maybe to be talked about to Ben.

But what he does know is that he's missed Diego and he's hurting and he doesn't want to fight with his brother, even if he still feels hurt.

"Here, I'll show you." he says, shifting carefully and pulling off the long-sleeved shirt he's wearing. Underneath, his body is marked up in multiple places with aging bruises, yellow and purple and grey, there are shiny pink cauterized wounds from laser burns and scabs over cuts and scrapes. The most prominent injury is covered with a bandage right now - a neat white square just under the ball of his right shoulder.

"I got hit with a brain scrambling beam and stumbled around. Landed on a branch." he says, voice calm and sort of idle. Leaning his head back, he sighs softly.

"And no, I don't hear it. There aren't even any ghosts in here."
