I like thought-through theories better than just dropping a single line anyway ;)

But there is one problem with the "ice colour" point. Ul and Ultear's ice were quite differently coloured despite being mother and daughter. Ur's ice was blue-green (actually halfway between Gray's and Lyon's ice if you ask me) and Ultear's was lilac.
