Once Upon a Time Season 2 returns from its three week hiatus this Sunday (April 21) with Season 2, Episode 19: “Lacey." But if waiting until this weekend is too long, we're here to help with all of the juiciest spoilers about the episode gathered in one place.

Who is Lacey? As this sneak peek shows, Regina "jogs" Belle's lost memories — with a lie. She now thinks she's a barfly named Lacey. As Emilie de Ravin described to us, Lacey is a "free girl" who "has her own mind." She enjoys hanging out at bars, and she's drawn to Mr. Gold's dark side.

So, what about Gold? According to the official synopsis, "Mr. Gold enlists the aid of David to help him try to jog Belle's now cursed memories and get her to love him again." According to Emilie, he faces a lot of conflict when he realizes Lacey is drawn to his dark side: "I want Belle back, but this girl is accepting me for who I am, being dark. But then, I need Belle because she makes me a good person." Whatever happens, it sounds like there will be plenty of Rumple and Belle/Lacey scenes!

Gold and Henry. The question of what Gold should do about Henry — who is prophesied to be his undoing, after all — also comes up this week. Based on this script sneak peek, it sounds like he's certainly going to think seriously about killing Henry, even if he doesn't go through with it.

Should they stay or should they go? The official synopsis also says "when it is revealed that the magic beans Anton (Jorge Garcia, "Lost") and the dwarves have been harvesting have begun to grow and could possibly transport everybody home, Emma is torn over whether she would want to live in Fairytale Land or stay in our world."

Robin Hood. Meanwhile, the flashback portion of the episode will dig deeper into why Belle fell for Rumple in the first place, with a story set during the "Skin Deep" period. The official synopsis says "Rumplestiltskin  forces Belle to accompany him on a hunt to kill a thief, whom she had freed in the name of mercy," and we know the thief in question is Robin Hood. However, don't expect a deep exploration of Robin — we might learn more about him down the line, but for now we won't get a whole big backstory on him.
