So I finally talked with Cake finally after some years. A hyperbole of course since I really haven't meet him for that long. Anyways, he seemed like a pretty nice guy. So he gave this idea they maybe Millie could go headless through some sort of spell. Considering Millie is an mage it was certainly in the realm of possibility. So I figured why not? This isn't going to be forever since the being headless is Cassie's shtick. However, through magic she really can take her top off. lol
Anyways, side note. I just read Cassie's abridged back-story here on Cake's Tumblr and I found to quite intriguing. I will probably come up with for Millie in the future. Just need to decide on a few things.
