ABC has released the first sneak peek from Sunday's episode of Once Upon A Time: "Nimue."
In it, Merlin lays out his plans of making Excalibur whole again to Zelena, Hook, Mary Margaret, David, Regina and Robin. It's a dangerous mission, but it may save Emma's soul from the Dark One. When Merlin explains to Hook the future isn't certain, he loses his cool. "You're willing to send us behind enemy lines but when it comes to specifics everything is a little fuzzy, isn't it" Hook snaps.
Check out the clip in the video below.
In Camelot, Merlin spearheads a mission to reunite the dagger with Excalibur so he can use the weapon to save Emma from the darkness threatening her soul. With Zelena in tow, Hook, Mary Margaret, David, Regina and Robin steal into Arthur’s castle to take the broken sword from the maniacal king. Meanwhile, Merlin brings Emma along on a journey to confront his ancient nemesis and retrieve the sacred spark he’ll need to reforge Excalibur. Both parties are tested, but one suffers a blow that could derail the entire operation. In a flashback to long before the Age of Arthur, young Merlin finds purpose after he is blessed with magic and immortality, but when he falls in love with a young refugee named Nimue, everything changes for Merlin, as their romance starts a chain of events that touches every one of our present day heroes.
"Nimue" episode of Once Upon A Time will air Sunday, November 8 at 8:00 p.m., ET on ABC.
