Idek how to describe Plaus's dynamic succinctly but it's like.
P feels something akin to a crush for Klaus. Like, he admires him, and thinks he's really cool, and wants to be a little more like him (explore the world and collect all the little trinkets).
Meanwhile, Klaus just thinks P is a very fine young gentleman and can't help but dote over him. He is a little flirty, yes, but to him, who's used to rubbing elbows with so many people, it's not really anything of note. But to P, the constant compliments are starting to get him worked up......
Lumacchio's watching all this from the lobby and is honestly jealous the attention isn't on him. Not like he was initially into either of those two! But, really! Isn't he of more interest than some dusty old trinkets???
