With only a few hours left to go until the Once Upon a Time Season 5 fall finale, I've already started counting down the days until its return, which — might I add — feels insanely far away. (For those of you who don't already know, OUAT won't be back until March 6 of next year! *cue the sad violin music*) But if there's one thing that will help pull us through these dark days and see the light at the end of this hiatus tunnel, it's Once Upon a Time 's 100th episode special, which will be jam-packed with a ton of very familiar faces. Aside from all of the usual main stars, OUAT 's 100th episode will see the return of many beloved characters — even a couple from the great beyond.
That's right, folks — this series isn't going to let something as tedious as death prevent them from stopping by for this very special episode. And my gut tells me it will have a little something to do with Hook's upcoming Underworld plans. After all, we know that Hercules and Meg have been cast to appear in Season 5B and Once co-creator Eddy Kitsis described the latter part of the season as being "hell" at this year's New York Comic-Con. So I'd say death is about to become a relative term for these fairytale folks.
But enough with all this theorizing! I've taken the liberty of rounding up the Who's Who of returning guest stars to help get you even more excited for the big event. And if this list is any indication, it's going to be one heck of a magical night, dearies.
Robbie Kay As Peter Pan
It'll be interesting to see how this new heroic version of Rumple will handle coming face-to-face with his dear old dad. Something tells me this will make for one very tense family reunion.
Barbara Hershey As Cora
Speaking of awkward family reunions, we'll also get to see Cora reunite with Regina. I wonder if this will drug up old feelings about how Cora's death came about. (Watch yourself, Snow!)
Tony Perez As Prince Henry
And just to make Regina's family tree complete, Entertainment Weekly has also exclusively learned that her dear old dad Prince Henry will also be making a cameo throughout the hour. Yeah, I'm sure things aren't going to get awkward at all.
Emma Caulfield As The Blind Witch
We haven't seen this character since Season 1 when Hansel and Gretel gave her a taste of her own medicine, so to speak, by locking her in an oven. (That karma will get you every time.) But maybe this means you're allowed to own gingerbread houses in hell? Sounds tasty!
Giancarlo Esposito As Sidney Glass
Magic Mirror on the wall, what will Sidney's return mean for us all?
Jamie Chung & Meghan Ory As Mulan & Ruby
While it has yet to be outright confirmed that these two badass ladies will show up in this specific episode, I'd say there's a fairly big chance that we'll see them appear at some point. For starters, both actresses signed on for multi-episode guest arcs and so far we've only seem them in one. Plus, if our Storybrooke characters are about to face the likes of hell and possibly even Hades himself, it wouldn't hurt to have a warrior and wolf on their side.
So as you can see, anyone who's anyone is going to be apart of this episode. (Well, aside from Graham and Jefferson, unfortunately.) And I, for one, can't wait to see how this magical storyline will unfold. Is it March yet?
