Split personality appears to be the main theme of “Once Upon A Time” Season 6, Executive Producer/writer Adam Horowitz has teased. The new characters being introduced in the TV series will apparently be used to reflect the personality of the heroes.

[Spoiler alert]

The introduction of Dr. Jekyll (Hank Harris) and Mr. Hyde (Sam Witwer) allowed the writers to bring back the Evil Queen inside Regina (Lana Parrilla). But she may not be the only one fighting against inner demons, the next season will reveal.

“The intent is that these new characters and new stories are really a reflection on what’s going on inside of our characters,” Horowitz told Entertainment Weekly. The new characters he is referring to are the ones from The Land of Untold Stories, who have travelled to Storybrooke along with Hyde.

“With Lana and the Evil Queen, that’s the starkest example, which we’ve already teased. We’re literally going inside her and pulling her apart. There are elements of that that we’re planning to do for each and everyone of the characters,” Horowitz said.

A big change in “Once Upon A Time” Season 6 is the format. The heroes will not be seen fighting Hyde for 10 episodes and then win in the winter finale, which has been the format for the past few years. Instead the show will go back to its Season 1 roots, in which stories of different characters was featured in each episode.

Executive Producer Edward Kitsis previously told Entertainment Weekly that the show will now focus on “small town stories and smaller arcs.” Horowitz revealed that “Once Upon A Time” Season 6 will be a 22 episode long story, instead of the season being split into two halves. He teased that the story will force the main characters to look “inward,” but they will not be split into two like the Evil Queen.
