Howdy and welcome to the game! I'm BB and my boys are the Professor and Charles. Both are humans (a sorcerer illusionist, and a psychic cowboy), and have been around Zion for a little bit. Professor Blackstone for 11 years (joined up in 1908), and Charles for 2.
James likely has no real clue who Juliette is unless they've crossed paths during meal times or unless she's been to see his 'show'. For the most part he is relatively oblivious/lost in a world of his own making thanks to his magic. Still he's well dressed, well read, and adores a good book. He's also been the companion (or pet if you ask Eva) to another vampire dancer with at the Carnival.
Charles is well dressed, and something of a cowboy/gentleman when he's not drunk or high. To be fair the rye whiskey and laudanum are all that help with the migraines he gets from using his powers...even though the man has no clue that he possesses any abilities at all. Still, he's likely enjoyed watching Juliette dance over the years, if not enjoyed a private show too if you wanted. He's probably never been a snack for her though since the man's luck seems to be insanely high and he always slips out of trouble without trying.
