Hello, Heather, I'm Jamie and I have just the one character here, Llewelyn Maddoc.
Llewelyn is a medium to the nth degree, stemming from his mother's side of the family (she, too, was a medium and committed suicide because of the crazies when he was about thirteen). He's been haunted since childhood and has had demons on his ass since around then, too, though since emerging from the lovely cocoon of adolescence he's managed to wrangle some of those into submission in order to do his bidding and a) help him with his act, b) hunt down the demon who drove his mom nuts. Llewelyn's 20 years old, kind of a little bitch sometimes, woefully sarcastic, ambitious as hell, and sometimes a little fucking freaky.
Llewelyn likes the burlesque dancers for the most part on principle, because he likes looking at pretty things, but I'm not sure how typically he interacts with them. I have a feeling he won't much care for Annie (and will find her stage name personally hilarious), but that's not unusual, as he tends to care little for people he can't use in some way. However, that's no reason not to throw them together!
As for Simon, his gift might be cause for Llewelyn to seek him out at some point, though it might be easiest for us to go with the they-haven't-quite-met-yet so we can get in a first impression. Unless you'd rather have them have already met, which is also fine by me!
I'm always pimping Llewelyn's demons out to others, so if there's any backstory you'd like to explore with either of your kids that the ghosts/demons might aid in via Llewelyn, let me know! You can reach me through my contact post in this journal :]
