"Jack Frost." For all the sudden feelings of caution thanks to a certain pair of inebriated mediums, Jack feels silly staying up in the tree while he's talking to this Giles person. He's not going to go around being afraid of regular adults now, he decides -- and he's pretty sure that's what this guy is; other kinds of beings are usually pretty obvious. It's just smart to be a little bit careful, that's all. He steps lightly off the bough and a brief draught kicks up for a moment to break his fall and allow him to land lightly on the floor near Giles...but out of arm's reach. "I'm guessing you don't know who wrapped us up, either?"
