"Once Upon A Time" season 4 spoilers show a Regina fighting against her dark side with the help of her adopted son, Henry. Meanwhile, Jamie Chung expressed her desire to reprise her role as Mulan although the "Frozen" story arc will make it difficult to accommodate her wishes.

Showrunner Edward Kitsis teased "Once Upon A Time" season 4 spoilers to Entertainment Weekly as he said: "We're going to see Henry on a mission with Regina this year, and maybe some of his light side will rub off on her."

The return of Maid Marian with no small help from Emma Swan has thrown Regina for a loop as Robin Hood finds out that his wife is alive. And rumors are flying that it could trigger her into taking on the mantle of the evil queen again.

Henry has always been a kind kid and has been the perfect yang to Regina's yin. And actor Jared Gilmore talked about the evolution of Henry through the time, particularly after his stay in Neverland.

"Since the first season , he's definitely more mature and can stand for himself," he said in an interview with KSiteTV.

But executive producer Adam Horowitz teased "Once Upon A Time" season 4 spoilers to TVLine when he said that there's going to be no conflict between Regina and Robin Hood over the return of Maid Marian.

"Who says we're doing a love triangle? Hopefully it becomes less about the relationship itself and more about Regina [and] open[s] the door to who she is and what she's going to become," he said.

Meanwhile, in an interview with E! News, Jamie Chung basically told Edward Kitsis and Adam Horowitz to provide a conclusion to her Mulan character, even if it's going to be a love triangle between Aurora and Elsa.

"I love them and I hope the feeling is mutual but I don't know! I just don't know if it fits into their overall story arc. As you know, they have 'Frozen' on this season so that's a very big deal. I guess it all just depends where the story goes but I've offered my services," she said, adding that, "I feel like her storyline was kind of left up in the air."
