That's great! Well, I think Aria needs friends because at the moment Adam and Tavish have enough.
I think Dreizel and Izzy would make good friends. Dreizel is always curious about other people. Also, I think Dreizel can test her by being mischievous towards her, which can set off further discovery about her other abilities, if you want :)
Aria and Jessica could become friends as well. Aria makes music, which is one of the things Jess likes, so that can work for them. Also, Aria makes cookies and other little snacks that she makes herself, which aren't that good yet. Maybe Jess can help her with that.
