"Once Upon a Time" season 4 spoilers show that new cast Sally Pressman is very excited about her gown-wearing character, as Queen Elsa and Emma appear to be forging a new friendship.

According to the TVLine's "Once Upon a Time" season 4 spoilers, Sally Pressman of "The Army Wives" was included into the cast of Storybrooke characters, as announced by the actress in her Twitter account last Friday where she wrote: "There were extensions, eyelashes and gowns...and a very happy actress."

"The content of Pressman's tweet (extensions?!) suggests that she will be playing the dearly departed mother, likely in flashbacks, to 'Frozen's' lavishly locked sibs Elsa (Georgina Haig) and Anna (Elizabeth Lail), although that has not been officially confirmed," the website said.

Executive producer Edward Kitsis dished out "Once Upon a Time" season 4 spoilers to TV Fanatic as he said that Emma and Queen Elsa will strike a friendship.

"I think you're going to see that Elsa and Emma are going to have a friendship that we're going to see play out. I think we're going to realize that they have a lot in common but the 'Frozen' arc is definitely going to be affecting everybody," he said.

Meanwhile, executive producer Adam Horowitz also dished more "Once Upon a Time" season 4 spoilers regarding Regina's fate now that Marian is back and could mess up what she had with Robin Hood. Rumors are flying that she might revert back to her evil ways due to a broken heart.

"Regina's a constantly-evolving character. She's not going to revert to what she once was because people don't generally do that," he said. "But what we want to show with her is what we think people often do, which is they move forward but the elements of who they once were are something that they're kind of battling."
