Emma Tries To Hook A Hero In Once Upon a Time "Siege Perilous" Sneak Peek

Entertainment Tonight has gotten their hands on a new clip from this Sunday's episode of Once Upon A Time: "Siege Perilous."

Hook (Colin O'Donoghue) brings his brown bag lunch back to his Jolly Roger when Emma/Dark Swan (Jennifer Morrison) magically appears. He's not a fan of her entrance, but she tries to swoon him by recreating their first date -- grilled cheese and all! This is all a deception to win Hook over so that he will be the hero that pulls Excalibur from the stone. Will it work? You'll have to tune in this Sunday to find out.

Check out the sneak peek in the video below.

In Camelot, the heroes feverishly work to free Merlin. Determined to help Emma, David embarks on a quest to retrieve a magical relic that Regina could use to communicate with the imprisoned sorcerer, but, when David leaves, ARTHUR insists on joining him because the dangers ahead are greater than he can imagine. Meanwhile, Mary Margaret discovers the fate of her old friend Lancelot. Back in Storybrooke, ARTHUR seeks David's help to catch a thief who threatens the safety of the citizens of Camelot. Across town, Emma reaches out to a conflicted Hook as she sets about her plan to draw Excalibur from the stone.

"Siege Perilous" episode of Once Upon A Time airs Sunday, October 11th at 8/7c on ABC.
