Oh, I feel like the impostor theory has definitely become my new _____ is definitely Bae theory. Hee, there’s so many possibilities on who Cora could possibly impersonate that in a way I hope it doesn’t diminish the theory too much. I mean I admit there’s a lot of holes in it if Cora impersonates Snow, but I think they gave her the ability to shape shift into other people for a reason besides just finding about the wardrobe. I think it would be like how in Harry Potter, Polyjuice Potion and someone being an unregistered animagus came up throughout the series not just brought up once and never used again. Although for OUaT, I don’t think they should overuse the idea if in fact they went that way, but in order to make Cora feel like a real threat but work around Barbara Hershey’s schedule, since she’s not a regular, Cora impersonating someone in Storybrooke seems like a way to do that. Of course, it’s not the only
way, but it’s just one that seems the easiest to do right now, imo.
Anyhow, I thought this quote from an interview Jamie Chung did with ET was interesting,
ETonline: What are you excited for the fans to see this season?
Chung: I can’t give away a lot, but it gets stranger and darker. People are going to think we’re a cable show with how dark it gets. The dream [that Henry and Aurora share] is hugely important to the rest of the season. We discover that we can use to our benefit – but then, whatever can be used for good can also be used for evil. That’s a big theme in the next two episodes. What was once good can be used for evil, and vice versa. It’s really important to keep that in mind over the next two weeks.
Maybe she’s talking about Aurora’s heart being something that was good that’s now being used for evil, which definitely makes sense. However, before that she talks about the shared dream that Henry and Aurora have, so I wonder if that’s something that Cora and/or Hook will be able to manipulate to their advantage. The unconscious realm is definitely playing a major role this season, so that would certainly fit if Cora/Hook could manipulate the good guys in that realm as well as in the conscious world.
