Mia Lane is accepted. I feel I should tell you that milk is a liquid that does not have water in it, so you cannot control it. Blood, on the other hand, as well as any other liquid composed of a mix of water and something else, can be controlled so long as it retains liquid form. Only water and blood are able to be frozen or evaporated. Also, I'd like a more detailed explanation as to how she retains "vast amounts of knowledge.
Viktor de Masca is accepted. The only thing I have an issue with in your character is his cane. I realize you attempted to dumb it down, but the simple fact is that manipulating metal isn't one of the warlock's powers. You can have a cane that is also a sword, or perhaps some other tool, but you cannot change it at will.
