A new clip from the upcoming episode of Once Upon a Time was released Thursday, featuring a big spoiler about Peter Pan's (Robbie Kay) motivations with Henry (Jared Gilmore).

The new clip, which was published by Entertainment Weekly, features Emma (Jennifer Morrison) and the gang talking to a newly-freed Wendy about Pan's intentions. In the process, she reveals the real reason behind Pan's desire for Henry's heart.

"Pan told Henry that he needs his heart to save magic. It's a lie - he needs it to save himself," she explains to the gang. "Pan's dying. He needs the heart of the truest believer to absorb all the magic in Neverland, and once he does, he'll be immortal."

Wendy also reveals that in order for Pan to be immortal, Henry will have to die in the process.

MAJOR SPOILERS AHEAD:

In the photo, Mr. Gold (Robert Carlyle) is seen stabbing Pan in the heart, seemingly ending his life. Every member of the gang has also transported back to Storybrooke, with all of them being alive and presumably well.

This episode will air in December as part of the midseason finale.

Once Upon a Time airs Sundays at 8 p.m. on ABC.
