After Once Upon a Time’s epic Season 3 opener (“The Heart of the Truest Believer,” September 29), we don’t know what to think. Yes, Peter Pan is evil and effectively wants to rip Henry’s heart out, but there is still an air of mystery about Neverland. What can we expect from tonight's all-new episode (Season 3, Episode 2: “Lost Girl”)? The official synopsis of the episode reveals some clues.

"While Emma, Mary Margaret, David, Regina and Hook continue their search for Henry in Neverland, Peter Pan appears before a startled Emma and offers her a map that will reveal her son's whereabouts. But the only way to make the map appear is for Emma to stop denying who she really is and come to grips with her true feelings about her identity - and Mr. Gold receives some unexpected advice from a friend that could lead him to understand his life's journey while in Neverland. Meanwhile, in the Fairy Tale Land that was, when the Evil Queen presents Snow White with an offer to live her life with Charming in peace — with the caveat that she give up her claim to the throne — Charming makes it his mission to ensure that Snow doesn't take the offer."

With that information combined with the intel we gathered from the promo, it looks like we’re in for an exciting episode that hopefully includes a reunion for Rumbelle.

Of course, with the mix of present-day Neverland and flashback-timed Fairytale Land, it will be an interesting episode. Snow White and Prince Charming are seen approaching a sword in stone, which hints we could be seeing a new tale in addition to their backstory.

Honestly, we just want to see an action-packed episode, hopefully showing us the “Lost Girl” in question. Could it be Emma as she teams up with Peter Pan to save Henry, or is it someone new who we have yet to meet? Leave your thoughts and theories below, Oncers!

Catch the next episode of Once Upon a Time on Sunday, October 6 at 8 p.m. ET on ABC.
