Will Henry's (Jared Gilmore) dream of having one big happy family come true in season 6 of ABC's Once Upon a Time?

The eternally optimistic Henry is still hoping to live peacefully with Emma (Jennifer Morrison), Regina (Lana Parrilla) and Snow (Ginnifer Goodwin). However, the splitting of the Evil Queen from Regina will surely complicate matters.

Once Upon a Time co-showrunner Edward Kitsis spoke about this dynamic in a new interview with Entertainment Weekly.

"You get to see that this really is a family that has come together," Kitsis explained. "Henry's dream in the beginning was to bring everyone together, and in a lot of ways he has, but this year they're going to be tested from their past. If there's one thing the Evil Queen hates it's Snow White - Snow White and other people's happiness."

ABC also released the press release for the season 6 premiere, titled "The Savior", revealing how Regina and Emma in particular will be dealing with plenty of drama in their lives.

"When Regina split herself in an attempt to eliminate her evil half, she unwittingly released the Evil Queen," the synopsis reads. "Now the Evil Queen is back and ready to leave a trail of destruction in her wake. Meanwhile, Regina is quickly learning that destroying her dark side won't be that easy, especially when dealing with the consequences of having unleashed the Queen on Storybrooke. Emma learns a life-altering secret that could have serious consequences for her family and loved ones. While the heroes grapple with what Emma is confronting, Henry welcomes the new arrivals from the Land of Untold Stories by pledging to help them complete their tales."

Once Upon a Time season 6 premieres Sunday, Sept. 25 at 8 p.m. ET/PT on ABC.
