Carnévale likes music ofc. The carnival has a rather large piano/pipe organ that he is infatuated with. He really isn't in any acts himself, he acts like second-in-command, guard dog, and an eccentric voice for event billings, an announcer of sorts. He does play music for the circus/freakshow portion during big performances, though. You'd never know it, but he doesn't really like humans all that much. He will treat the guests like gold, and he does like the children, but adults he is cautious while being courteous. Anyone that is a threat to his family, he might give a warning if the person is lucky. He also doesn't really like veggies. He's sorta a brat.
Lori likes pretty things. Dresses, jewelry, shiny knick-knacks. Things she could never afford and never got to have. She loves to sew, learning from Silvie on how to do so. She also likes romance novels, but that's her secret that she will take to her grave. For obvious reasons, she does not like loud noises. She's trained herself to handle how loud it gets during her rare performances, but sudden explosions or even fireworks can send her into a shock where she curls up to cover her ears.
Nick likes cheap cigars and whiskey. He also likes naps. And pretty ladies. He's a typical bum man in that time period. But he does like making people laugh, seeing other folk's joy. He never had the opportunity to live a normal life with a wife and kids, a normal job, a normal house. Despite being a grumpy ol' butt, he cares about his family, and especially likes playing the dad card with Lori. He doesn't like smartasses and people with ego, and in perfect character will totally bring down some young men and embarass them infront of everyone while still being a silly clown.
