The Skeleton
Skylar actually blinked in surprise when the Skeleton did a three pirouette in the costume. "Our Skeleton's a dancer then..." she mused as she watched the clue.
Once he sand his song, Skylar spoke first. "So, you're normally a dancer who happens to sing quite well. That...doesn't help me much other than maybe eliminate a few maybe guesses I had in my head after your last performance. I don't personally know of any practicing warlocks or mages who are also dancers. Hell, I'm really wishing I were better at guessing. You being in the attic, is that a clue as well?" She really wasn't sure about this one.
