"Once Upon a Time" Season 3, Episode 8, "Think Lovely Thoughts" delve deep into the backstories of the two big enemies this OUAT season: Rumplestiltskin (Robert Carlyle) and Peter Pan (Robbie Kay). The former knows Henry Mills (Jared S. Gilmore) is his undoing; the other, his only hope to save magic in Neverland. Are both of them out to kill Henry to save themselves? That is one of the OUAT 3 questions.

Once Upon a Time Season 3 has so far shown only one episode in Storybrooke. All action has been in Neverland. Two teams are trying to save Henry from Peter Pan. One is the duo of Rumple aka The Dark One and The Evil Queen (Lana Parrilla), biological grandfather and adoptive mother of the young boy. There are more people in the other group, "fifth wheel" included. Regina Mills aka Evil Queen used to be a part of this group, but switched camps, tired of Pan's games. But there might be another switch coming - see the OUAT 3x08 sneak peek video below.

Mary Margaret aka Snow White (Ginnifer Goodwin), David aka Prince Charming (Josh Dallas) have discussed the possibility of both of them not leaving Neverland. Their daughter Emma doesn't want her parents to "abandon" her again. What "way" will they use to get out of Peter Pan's island alive?

Emma Swan (Jennifer Morrison) calls the OUAT 3 Save Henry mission "Operation Cobra," a continuation of Henry's quest for a happy ending. "The Charmings" are joined by Rumple's son Baelfire, and the lover of Henry's grams (also a potential stepdad), Captain Hook. Watch the sneak preview below. Henry Mills certainly has one very odd and dysfunctional family!

OUAT 3 Big Question: Will The Dark One Save Henry?

Baelfire aka Neal Cassidy (Michael Raymond-James) knows Captain Hook (Colin O'Donoghue) and Emma have shared a kiss in Neverland. But he's not giving up on Emma Swan just yet. In the meantime, he's reunited with Rose McIver' Tinker Bell (just old friend?) to save Henry and execute their Neverland exit plan.

Baelfire doesn't believe his dad Rumple will not kill Henry - in Neverland or Storybrooke. The old man's quest for redemption is marred by his "old habits." In Once Upon a Time Season 3, Episode 8, Rumple's past will be exposed. This is believed to be the episode that will tackle his father's story. And their old connection to Peter Pan.

Once Upon a Time Season 3, Episode 8, "Think Lovely Thoughts," airs Nov. 17 in the U.S. network ABC. It is followed by three more Neverland episodes, culminating in "Going Home" (Episode 11). OUAT takes a break after this, and the show will return in March 2014.
