You're scared, and your immediate thought is that you want your sister. You haven't seen her since you wronged her (He was a jerk, though), and you aren't even on speaking terms. You don't even know where she is, but you want her all the same.
The castle is dark and dank, and you're frightened, and you know she would have something sane and logical to say when your fears get the best of you. She was always that way, the calm one. You're the one that flies off the handle and does stupid things, and you've never wanted her with you as much as you do then.
But she's not there, and you're following a floating candle down a hallway, after being traded for some stolen groceries, and you think it might be punishment. You ruined your sister's marriage, and this is the price you have to pay. Being here with this monster who is nothing like the sweet bear of your childhood.
