The Wicked Witch's true identity was finally revealed during Sunday's Once Upon a Time. And while her lineage wasn't a huge surprise, we did get some insight into whyshe cast the new curse and we also welcomed back a familiar face. No, we're not talking about Ruby (Meghan Ory), who made the briefest of appearances.

In Storybrooke, Hook (Colin O'Donoghue) reveals that he left the Enchanted Forest before the new curse was cast, which is why he still has his memories. He received a note that came via a bird — a la what Snow White (Ginnifer Goodwin) would normally use — that told him to retrieve Emma (Jennifer Morrison). Unfortunately, things are getting worse in town, with some fairy-tale characters mysteriously going missing.
