The last episode of "Once Upon A Time" ended in such a high note. There is an imminent war in Storybrooke and even the show's bosses think that the war is going to be really bad. The war is going to be more about dealing with personal issues and how the characters would overcome it.

Season 6 episode 11 shows Emma and Regina trapped in an alternate universe with Robin, where Regina reconnected with an alternate form of her lover. In "Once Upon A Time" Season 6 episode 12 titled "Murder Most Foul," Regina will discover Robin's dark side.

The official synopsis of the upcoming episode says that Regina works to acclimate Robin to life in Storybrooke, but she will soon find out that he has an evil side, ComicBook Movie reported. This discovery will make the task much more complicated and Regina had anticipated.

How does this new version of Robin adapt to Storybrooke then? During an interview with E! News, co-creator Edward Kitsis said that Storybrooke would be wary, especially Regina's friends because this is not the same Robin Hood. Regina has been trying really hard to remove the darkness from her and move forward, so finding Robin's dark side will definitely be a test.

Kitsis also added that all these talks of war in Storybrooke is going to get bad. Co-creator Adam Horowitz hinted that it's not just going to be about the external conflicts, but also internally as all the characters would have to look inward and deal with their own issues.

Meanwhile, before Hook can take the next step in his relationship with Emma, he wants to make sure that David does see him as a mere pirate. And so he agrees to help David uncover his father's death. "Once Upon A Time" Season 6 episode 12 will air on March 12.
