I'm just going to talk about Midnight so Luna Midnight can get her part in the story...
So, she's friends with Tom, but not friends with Lucas or Asia. She never meets the two others, because she's not interested in them. Plus, I don't think there is anyway Asia and her to meet though, the year has already started. Anyways, ya. I write the twins POVs, so Midnight will only be in my stories, so if you want to have a chapter with Midnight in it, look for mine. I can't really turn her to a cat, because Asia can already do that and it'll make some sort of conflict, and since that is something special about Asia, I think all of them need their own special thing to do. And if you ever want her to be a werewolf, just be reminded to look how a Harry Potter werewolf looks like, they are NOT pretty. Anyways, I will try to include her often. If there are any requests you'd like, contact me for Midnight, since I will be writing her.
