I've got Theo - another Magus, and supposedly a fortune teller (conwoman who works with luck rather than the direct future), but she's definitely probably sent people his way since even her lying can only go so far. And since he's the real deal, she'd probably be eager to send people genuinely looking for a medium his way instead of trying to play them.
Nicolas - shifter who sticks to the back-lots. He's been with the carnival about six years, so he's definitely seen him, but probably would only interact during set-up since he tends to stay with the animals. Given his personality though, if they ever did interact, Nic would probably like 'im! He's better with other quiet people.
