'Once Upon a Time' Season 5 Episode 10 Spoilers: Hook Will Go on a Rampage as The Dark One

The new episode of "Once Upon a Time" will air two weeks from now, and fans will see Hook (Colin O'Donoghue) on a rampage, now that he is possessed with dark magic.

Last night's two-hour special from ABC ultimately revealed Emma's (Jennifer Morrison) dark plans, which were teased all throughout the first part of the fifth season. According to TV Line, Dark Emma wants to transfer the dark magic within her to Zelena (Rebecca Mader), and once it's complete, Emma will strike the Wicked Witch of the East to finally vanquish the evil.

However, her plan came to a halt after learning that Hook's injury from the Excalibur during his battle against King Arthur (Liam Garrigan) will eventually kill him. Not wanting for the pirate to die, Emma uses her dark powers and the sword to turn Hook to another Dark One.

In the sneak peek of the upcoming episode of "Once Upon a Time," which is entitled "Broken Heart," the teaser said that "there is nothing worse than a vengeful pirate with dark magic." Viewers saw Hook on a rampage now that he's filled with dark powers. He even challenged Rumpelstiltskin/Mr. Gold (Robert Carlyle) to a sword fight, saying, "Shall we finish what we started?" to which Rumple replied, "Indeed." He seems victorious in their fight, and fans saw Hook standing over the injured Mr. Gold.

Hook is also not yet finished with Emma, since at the end of the clip, he said to her, "I want to hurt you, like you hurt me," and Emma silently cries after. Fans are dying to know what will happen to the couple now that things are not the same as before between them. It seems like just a week ago when Hook confessed his love for Emma no matter what she had become, and now, he wants to hurt her.

Watch "Once Upon a Time" season 5 episode 10 this Nov. 29 on ABC.
