The posts appear to have been taken down from Instagram. Here's the full poster from the wiki though: [1]

Looking for an archive of the post captions. I'll post them once I find them.

Here is the poster parts and the clues.

But yet; nothing about a potential Rapunzel.

Ah, thanks. I had just finished scrolling through Storybrooke Mirror to find nothing and wasn't looking forward to doing the same thing for EF News Service, lol.

"We're positively glowing" definitely points towards Rapunzel over Alice: "Flower, gleam and glow." The Flowers in Alice's story talk a lot but they never glow.

But it is definitely weird that they would tease Rapunzel leading up to ComicCon and she's the only one not mentioned. The options for what that could mean seem obvious:

1. The clues aren't just teasing for ComicCon, they're teasing in general (and Rapunzel will be revealed later or is the Witch)
2. Rapunzel was revealed at ComicCon and plays multiple roles (if this is the case, probably Lady Tremaine, Drizella, or Alice)
3. The flower doesn't actually refer to Rapunzel (and could refer to Alice or Drizella somehow)

I'm beginning to doubt that the icons refer to specific characters since there appears to be no reference for Drizella and there are two references to Alice (the cat and the rabbit). If they're teasing in general, we could still see a second Alice character for the cat and Drizella just wasn't being teased like how the Prince, Witch, and Suited Heavy apparently weren't.

I still believe that one between Tremaine and Drizella could be Rapunzel. And it would be a good twist!

Witch = Gothel + Tremaine = Rapunzel turned evil is one of my theories since they announced Emma Booth's casting ^^

Was think that too. Gives Tremaine a reason for wanting to be royalty.

That would be an interesting and different take on Rapunzel, that's for sure.

That would be cool

I like this idea!

Maybe the Witch is both the witch from Rapunzel AND Rapunzel turned evil, since she is a blonde.
