Salutations, fellow caretaker! But wait, Charly is the caretaker for... them...
So year, Kit don't like Charly very much right now. It's probably unfair, unless Charly was all aboard the coming in like a wrecking ball train, but it doesn't seem like she was so gungho about the whole thing. Still, Kit's all about playing the blame game, at least initially. Of course, he's not nearly intimidating enough to make threats, so he's kinda harmless, and since Charly's been around his whole life he knows she's tougher than she looks. Certainly tougher than him.
Pre-annexation and expulsion, I could see something more akin to a mentor/student relationship, since they have similar roles, or maybe not.
