Regina reconnected with a different form of her lover Robin in Sunday’s midseason premiere of “Once Upon a Time.” Unfortunately for the former evil queen, the ‘villains never get a happy ending’ theme will seemingly continue in next week’s installment.

ABC’s synopsis for Season 6, episode 12, “Murder Most Foul,” reveals Robin (Sean Maguire) has a “dark side.” New to Storybrooke, Regina (Lana Parrilla) will try to help him acclimate to live in the human world, but things won’t go as smoothly as she hoped. “She soon discovers he has a dark side, which complicates this transitions,” the summary states. The promo video shows Robin shooting an arrow at a Storybrooke resident. Could he be the reason for the deadly episode title?

Elsewhere in episode 12, David (Josh Dallas) will bring his daughter’s love, Hook (Colin O’Donoghue), to help him with a big task. “David searches for the truth about his father’s death, and he seeks Hook’s help in this endeavor,” states the summary. A sneak-peek photo from episode 12, released on Twitter by co-showrunner Adam Horowitz, reveals Hook and David’s journey will include a few flashbacks.

And while Emma (Jennifer Morrison) may be fighting her fate that she’ll die at the hands of Gideon (Giles Matthey) this season, Horowitz and Edward Kitsis have told fans there will be happy time ahead for Captain Swan. An additional synopsis from ABC reveals Hook wants to “make sure David sees him as more than just a pirate” before taking the next step with Emma.

“We will see happier times. Even when the show is at its darkest or most intense, we always find the hope and we always find the fun,” Kitsis told Collider. “The entire show started with a wedding and that was interrupted by the queen, and today, they’re all best friends. That’s what we do.”

“Once Upon a Time” Season 6, episode 12 airs Sunday, March 12, at 8 p.m. EST on ABC. Watch the preview below.
