'Once Upon A Time' Season 6 spoilers: Another Dark One teased in leaked pictures

Leaked pictures from the production set of “Once Upon A Time” Season 6 tease the return of a Dark One. Another set of pictures show Regina fighting with the new villain Mr. Hyde. Meanwhile, Giles Matthey has been cast to play the role of Morpheus.

[Spoiler alert]

With split personalities being the main theme of the next season, some of the other characters in the TV series may also go through the same problem that Regina (Lana Parrilla) faced. Leaked pictures from the set posted on YVR Shoots show Emma Swan (Jennifer Morrison) fighting with a hooded figure that appears to be a Dark One.

Will Emma be fighting the Dark One inside of her? Or is this a new character altogether? All the powers of the Dark Ones are now inside Mr. Gold (Robert Carlyle), so it is not clear who this hooded figure is.

The title of the premiere episode of “Once Upon A Time” Season 6 is “The Savior.” So, the plot may once again focus on Emma this time around. Some behind the scenes pictures from the set have been posted in another report by YVR Shoots. Most of the heroes, including Regina, Hook (Colin O’Donoghue), David (Josh Dallas) and Mary Margaret (Ginnifer Goodwin) can be seen in the pictures.

Another set of photos posted on YVR Shoots shows a confrontation between Mr. Hyde (Sam Witwer) and Regina. Although she appears to be losing in the beginning, the pictures show the heroes succeeding in subduing the villain towards the end.

Meanwhile, Entertainment Weekly reports that Matthey has been cast to play the Greek god Morpheus in “Once Upon A Time” Season 6. The character has been described as a “quick-witted and insightful god of dreams.” As Belle (Emilie de Ravin) is under a sleeping curse, the new character will get to interact with her as well as Mr. Gold. However, Morpheus has the ability to hide his own agenda while being able to read the minds of others.
