In on of the shots of the WWW standing in Regina’s clothing, she is holding a strand of hair.
Check out the larger image of it that @OnceABC is using as their background image at the moment. It looks like she’s holding a needle, which I assume will have something to do with the dripping blood in the promo.
What if Rapunzel IS the Witch in disguise?
There’d still have to be an actual Rapunzel though, if that guy we think was playing her father was actually her father. We never got any hints of a mother being cast though, which leads me into this next quote…
“The Grudge describes a curse that is born when someone dies in the grip of a powerful rage or extreme sorrow. The curse is an entity created where the person died.” Could Rapunzel have something to do with The Dark One?
Maybe her mother died? BTW, the next part of the wikipedia description: “Those who encounter this evil supernatural force die and the curse is reborn repeatedly, passed from victim to victim in an endless, growing chain of horror. The following events are explained in their actual order; the original film is presented in a non-linear narrative.” It does sound rather Dark One-ish. Though for Rapunzel to be tied to the Dark One Curse, wouldn’t she, and her father, have to have lived a looooooonnng time ago, so why are they seemingly alive in present day?
