Spoiler Alert: This feature contains major “Once Upon a Time” Season 5 spoilers.

The two episodes of “Once Upon a Time” Season 5 that aired last Sunday has unveiled shocking story twists. “Once Upon a Time” Season 5, episode 8 titled “Birth” has revealed the secret that Emma Swan/Dark Swan (Jennifer Morrison) has been keeping.

Captain Hook’s life was put in grave danger when the cut of the Excalibur sword on his neck did not heal from Emma’s magic. To save the man she loves, Emma has turned Captain Hook (Colin O’Donoghue) into a Dark One.

The promo video of “Once Upon a Time” Season 5, episode 10 titled “Broken Heart” teases that Regina/Evil Queen (Lana Parrilla) has found out about what Emma did to Captain Hook. Emma explains that turning Captain Hook into a Dark One is the only way to save him.

The promo video further teased that the Dark Hook, who becomes a vengeful pirate with dark magic in the upcoming episode, will be targeting his long-time nemesis Mr. Gold/Rumplestiltskin (Robert Carlyle). The Captain Swan fans should also be worried for the Emma Swan-Captain Hook relationship in the new episode because the Dark Captain Hook wants to hurt Emma like how she hurt him.

Another storyline expected to be explored in “Once Upon a Time” Season 5, episode 10 is Merida’s revenge plan against King Arthur (Liam Garrigan). Merida (Amy Manson) has found out that it was King Arthur who killed her father, King Fergus (Glenn Keogh), in DunBroch.

The new episode of “Once Upon a Time” Season 5 will not air on Sunday, Nov. 22, so the fans must wait for the return of ABC’s fantasy drama series with the episode that features Captain Hook as the second Dark One. “Once Upon a Time” Season 5, episode 10 titled “Broken Heart” is scheduled to air on Sunday night, Nov. 29, at 8/7 on ABC.
