Once Upon A Time "Broken Heart" Clips: Hook Has A Score To Settle With Rumplestiltskin

ABC has released two clips from this Sunday's episode of Once Upon A Time: "Broken Heart."

In this first clip, Apparition Rumplestiltskin (Robert Carlyle) becomes Dark Hook's (Colin O'Donoghue) guide and promises to help him get revenge against Mr. Gold. In the next clip, Dark Hook confronts Gold and challenges him to a duel while wielding the most powerful sword in the realm: Excalibur.

Check out the sneak peeks below.

In a Camelot flashback, Hook becomes a Dark One and his lust for revenge against Rumplestiltskin is reignited. When Emma and Hook disagree about their best course of action, the final pieces of the puzzle are revealed as events in Camelot catch up to the present and we witness a charged confrontation between the forces of light and dark that sends our heroes on a collision course with destiny. Meanwhile, in Storybrooke, Hook's centuries old lust for revenge against Gold puts both of their fates in jeopardy while Emma's love faces the ultimate test as she tries to convince Hook to turn away from the darkness before she, Mary Margaret, David and Regina embark on a new mission as an unsuspected evil is released.

"Broken Heart" episode of Once Upon a Time will air Sunday, November 29 at 8PM EST on ABC.
