I'm totally open to anything between Bells and Izzy. Amusing how they have almost the same name, too. Izzy's really different from her - crazy and outgoing - so it just might work for them to be friends. Izzy can try to pull her out of her shell and all. :D YAY PLOT!
I will definitely think on all of those, though I am most leaning towards a brother for Laura at the moment. I haven't decided where I'll put him, yet.
