If that really was Regina then I'm really starting to think Glyph was in on the deal. It's just too much of a coincidence that they stopped at that place. Leads me to think that Regina and/or Moss worked to get them into the group.
I would agree except for that Glyph seemed very wierded out by everybody in the bed & breakfast from the beginning. Like he'd have to be a really good actor in addition to a mage to pull it off.
But then again, Moss certainly showed absolutely NO surprise at seeing May and Bern strolling in. So could be something there.
Also, haha I hadn't noticed that one of the servant's name was "Escher"... would be funny if he was responsible for the crazy rooms and never-ending staircase
