One of the biggest burning questions going into Once Upon a Time’s Frozen-themed season opener is whether Elsa (Georgina Haig) will say one of her most cherished and well-known lines from the Disney film. (You can go ahead and turn the song on now.)

The producers have already said they won’t attempt a musical episode, but that still leaves the door open for Elsa to eventually say the line on the series. “There are nods to it, but we haven’t yet scripted actually having her say ‘Let it go,'” executive producer Adam Horowitz tells EW.

Still, there will be plenty of Frozen shout outs throughout the first half of season, including the introduction of Kristoff’s reindeer Sven, actually getting to meet some of Hans’ 12 brothers that were mentioned in the film and seeing a version of Elsa’s snow monster in Storybrooke.

“We’re trying to walk the line between what feels appropriate for our show or inappropriate,” Horowitz continues. “What we want to do is make loving nods to the movie and things that are iconic, but we don’t want to do it in a way where we’re making Elsa say catchphrases for the sake of it. We want it to feel organic to the show and also want gives fans of Frozen payoffs to the thing that they love most. Our hope is that if you watch, you’ll see that there are nods to many things from the movie as well.”

For her part, Haig is really excited for one particular nod to the film. “I would love to build a snowman,” she says. “That might also be hinted on at some point.” However, word is we won’t actually see Olaf.

Once Upon a Time returns Sept. 28 at 8 p.m. on ABC.
