On Sunday's all-new episode of Once Upon a Time season 5 episode 7, "Nimue," Merlin spearheads a mission to reunite the dagger with Excalibur so he can use the weapon to save Emma (Jennifer Morrison) from the darkness threatening her soul. With Zelena (Rebecca Mader) in tow, Hook (Colin O'Donoghue), Mary Margaret (Ginnifer Goodwin), David (Josh Dallas), Regina (Lana Parrilla) and Robin (Sean Maguire) 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.
In the sneak peek clips below, our heroes seek a way to save Emma from the darkness. Plus, Hook gives Emma a special gift before her dangerous journey. Watch these sneak peek spoilers and tune in SUNDAY, NOV 1 8|7c.
