They were all a fun read! I dunno how well Nicolas meshes but he'd try with a couple of 'em at least!
Nicolas is a very big fan of 'you don't ask me, I don't ask you', so he'd probably ignore most of the rumors, and as long as Kieran's cool with him not saying much, he'd probably find Kieran's show and the family stories really fascinating!
He'd be like. Unfailingly polite since he knows her, but to be honest, there was probably a little alarm bell going off in his head when he met Eva so he'd probably do his best to avoid being alone with her.
He does not go to mass, but since it looks like they're both in the communal tent, he'd definitely be friendly with him!
I could see Kerr probably being one of his favorites around the animals? If only because it looks like her telepathy makes her really good with them - and he trusts people the animals trust you know? And he's not one to pry, so he wouldn't much care about her past or care to find out that she actually is a she. He might question a few things, for himself, but in the end? Don't ask him, he doesn't ask you. And I would imagine it would be a few 'exotic' animals for something to the left of a freak show. Just from what I've been able to find, a menagerie of sorts, rather than show animals might be the way to go until someone decides to actually run the animal show?
