I can't remember the exact quote, but the bit where Emma has to remind Snow and Charming that, in normal towns, the Sheriff doesn't usually bring her parents along on interrogations made me laugh.
Also, when somebody suggested that "Doc" (as in the dwarf) might be able to perform the surgery in Dr. Whale's place . . . .
So, now that Dr. Frankenstein and the werewolf are bonding, how long before Dracula or the Invisible Man shows up?
