Why are you speechless?
I loooooved the episode! Ursula is my favorite Disney character and The Little Mermaid my favorite movie and Once did great on her episode! Though this is nothing like the Ursula we know, it was amazing!
They used a lot of Disney Ariel's story for Ursula and it did perfectly fine. I loved how she sang 'Fathom's Below'. <3
I also liked the appearance of Ariel. It was nice to see her and get a little mention of Elsa and what has been going on. Now she's back with Eric again, I guess. Hope to see her again next season. It is lovely to see her turn up once in a while.
THAT CLIFFHANGER though. So the Author is trapped inside the book. Didn't expect that. Amazing! And suddenly The Sorcerer doesn't sound as good anymore. Why did he trap the author?
EDIT: I am a little confused, because it seemed like Ursula left but she is confirmed to have filmed for multiple more episodes. Guess something keeps her in town after all.
