He tried to get onto the stairs
Kaz: Hey! You're not going to make it down those, they're too narrow...just wait up here ok? I'll go get Joe...I'll be right back...
He backed up and sat back down. "Ka!"
Kaz: I'll be right back, I promise!
Kaz walks downstairs quickly to find Joe
Joe had something
Kaz: Joe, Klaus needs you! And uh...he kinda went full wolf...he's saying something about a book...?
"A...book?"
Kaz: Yeah, I don't know what he's talking about either...
"Strange."
Kaz: Hm...well-can we go get him before he kills himself trying to get down the stairs?
