Liz rolls her eyes as if she has no clue what he's talking about, but her blushing gives her away.  Finally she just throws her hands into the air in exasperation and heads off towards the castle.  Once there, though, she realizes she hadn't been told any specific place to meet with her new teacher.  Deciding to just start at the most likely spot and work from there, she heads back to her own room.  Worst case scenario, if Cayn isn't there, she can make sure she doesn't have any grass in her hair before setting out to find him!
