There’s still a bit of a wait before Once Upon a Time Season 3 returns from its wickedly long winter hiatus, but in the meantime, there are still titles rolling out for episodes later in the season. The latest title to be revealed: Season 3, Episode 19.

“25 Days to go! Here’s a #OnceUponATime #titlespoiler! Hope to see ya March 9th! #WickedIsComing,” co-executive producer Adam Horowitz tweeted last week with a photo revealing that Season 3, Episode 19 is titled “A Curious Thing.” Not to sound cheesy, but we’re actually curious as to what this episode could even be about — it isn’t as straightforward as Season 3, Episode 16, which is titled “It’s Not Easy Being Green.”

Now that we know the Wicked Witch (Rebecca Mader) and Glinda (Sunny Mabrey) are both a big part of this season, we’re thinking this has something to do with Oz, but new clues from Examiner are giving us some great leads.

“The Silver Shoes … have wonderful powers. And one of the most curious things about them is that they can carry you to any place in the world in three steps, and each step will be made in the wink of an eye. All you have to do is knock the heels together three times and command the shoes to carry you wherever you wish to go.” — Glinda in Chapter 23 of The Wonderful Wizard of Oz

We’re thinking the person who will be clicking the silver shoes together is going to be the one responsible for bringing everyone back to Storybrooke. This ambiguous title just got a whole lot more interesting!

Once Upon a Time airs Sunday nights at 8 p.m. ET on ABC.
