Didn't expect Cristina Ricci so show up again, however briefly so that was nice. The whole thing with the clockwork heart and Isaac was a nice callback to both Edgar Allan Poe (The Tell-Tale Heart) and Mary Shelley (Frankenstein) and I'm all here for more gothic callbacks :3
I despise Enid's storyline. Just let her be happy T_T I did love getting more backstory on Morticia and Gomez though. And the Galpins.
Agnes really, really grew on me in the last few episodes and I hope she gets to be in the next season as well. And I hope Nevermore gets to come back. You can't close a place like that for good! Really excited for the next season!
