'Once Upon a Time' Season 3 Spoilers: Henry's Adoption Story Revealed, Rumple's Father to be Introduced

"Once Upon a Time" will finally answer some mysterious questions this upcoming season. 

The fairytale drama will reveal the backstory of how Henry ended up in Regina's (Lana Parrilla) care. "Before our Christmas break, we plan to show the why and the how of how baby Henry came to his new mother," co-creator Adam Horowitz told TVLine. 

The series will feature a host of new faces in season three, including JoaAnna Garica Swisher as the classic mermaid Ariel and Rose McIver as the tiny but feisty Tinkerbell. TVFanatic reveals that another part will be soon be cast: Rumpelstilskin's father. 

The Dark One's father will appear on episode eight of the series. It is not yet known how long his father will appear in the series, nor who is slated to play the part.

Rumple's father is the least of his worries in season two. Once the characters aboard the Jolly Roger arrive in Neverland, Rumpelstiltskin gets a clear warning from Lost Boy Felix in a sneak preview from the season three premiere. 

"If you're here for the boy, that makes you Pan's enemy," Felix says. "If you go against him, you will not survive."

Rumple says that his survival is not the question--the question is how many Lost Boys he will take down with him. Just as the two begin to hostilely walk away from each other, the Lost Boy throws something onto the ground-- an object seemingly from Rumple's past-- that brings Rumple to tears. 

Rumple and the rest of the characters' visit to Neverland will play out over a cinematic, 11-episode arc. 

A motley crew of characters are aboard the ship to Neverland to retrieve Emma's (Jennifer Morrison) son, Henry. New photos for the upcoming season show that the shipmates' interactions will be just as unruly as the stormy sea. The vessel's crew consists of Emma (Jennifer Morrison), Mary Margaret (Ginnifer Goodwin), David (Josh Dallas), Regina (Lana Parrilla), Rumple and Captain Hook (Colin O'Donoghue). 

Cocreator Edward Kitsis told TVLine that he enjoys the fact that the journey is composed of such diverse characters. "We're really excited about all of it," Kitsis said about the new season. "One of the things we love most is just having the group be together. It's fun seeing this trek with all of them."

Additionally, fans will soon find out what Greg (Ethan Embry) and Tamara's (Sonequa Martin-Green) "Home Office" is.

The second season premieres on September 29 on ABC.
