I just posted this in spoiler tags in a thread on the regular forum, but wanted to mention it here too.
The thread was about Cora’s powers, and whether or not Lancelot is really dead. I wondered if Cora can only shape shift into being someone she’s killed, or someone who’s heart she’s stolen. Then I remembered that Regina was apparently gonna be seeing Daniel’s ghost. Could that somehow be Cora appearing as Daniel in SB?
Edited to add another thought I had just now reading another thread. Maybe those ashes of the wardrobe that Cora collected wouldn’t have enough power to transport her, but would have enough power so she could astral project, in a sense. That could be how she’d appear briefly as Daniel’s ghost in SB, even if she’s not yet in town.
Edited again to add that maybe she doesn’t appear as Daniel’s ghost at all, maybe Regina actually sees Cora? I know that Barbara isn’t in the cast list in the first post of this thread, but perhaps it’s not a complete list yet?
