I sure hope so. Though it need not go so far as Rumple being EVERY creature in the Disney Animal Kingdom, I really prefer the idea of having established characters cameo as other “new” characters for a bit. The novelty of the “bring on new characters and then drop em just as quickly or make them related to Henry” formula stopped working for me in Season 2 and I’m underwhelmed by the current offerings for who should play Elsa right now (with the nostalgic exception of LOST’s Elizabeth Mitchell).
We’ve seen villains as heroes, how about heroes as villains (or just “misunderstood” ice monsters)? Although, I admit, Ana’s already run the spectrum of good to evil, I wouldn’t mind seeing more of her nicer side if they can get it to work. Ashley/Ella is a character they could probably expand on, though I have another candidate in mind. If they’re to meaningfully incorporate something as beloved as Frozen into what they already have, isn’t something like that better than bringing on what could amount to a whole new cast and having that take time away from the others?
…and, although Will coming to Season 4 is much-appreciated consolation, I’m still really missing OUATIW (feel free to interject with “Let It Go” references here). I’m going to need at least a little Once Upon a Time in (Winter) Wonderland in Season 4, ideally with Stan and Hershey as well. 😉
