Once Upon a Time Season 3 kicks off with a trip to Neverland, but the premiere won’t be just about who is racing there aboard the Jolly Roger. According to the official synopsis for Season 3, Episode 1: “Heart of the Truest Believer,” things are going to go south quickly as multiple people’s fates are revealed.

Read on for all the details:

As Emma, Mary Margaret, David, Regina, Mr. Gold and Hook enter Neverland to search for a kidnapped Henry, they're greeted by a school of not-too-friendly mermaids who threaten to end their search before it begins; Henry finds himself on the run from the Lost Boys with another escapee from Peter Pan's encampment; and Neal, recovering from his wounds, travels through the Enchanted Forest with Mulan in an attempt to learn the fates of Emma and Henry.

Whoa, so Henry escapes? That is a little soon, but we’re not complaining. However, we didn’t expect to see any mermaids until Episode 6 when Ariel appears. Could the Little Mermaid be not-so-friendly, too? So far, we know that she’s an adventurous and romantic spitfire, but we haven’t learned her true intentions. Looks like OUAT may be putting a new twist on yet another fairy tale!

As for Neal, we’re excited to learn that Mulan will definitely be helping him. Will she be reunited with everyone in Neverland, or will Aurora perhaps connect with Charming to reveal Neal’s fate? The possibilities are endless.

Catch the premiere tonight, Sunday, September 29 at 8 p.m. ET/PT on ABC.
