While most of the responces are what you would expect, it turned out some interesting tidbits. Here there be SPOILERS.
From the Huffington Post:
I think the producers have indicated in previous interviews that there will be a resolution to the Kathryn storyline fairly soon. So in terms of where you're filming now, has the balance shifted between Emma and Regina at all, or has Regina still got the upper hand? By the point we're at right now, it does start to balance out a little bit. There's more and more building against Regina in terms of proof for other people in town to realize that maybe, she isn't just a good mayor. Part of the curse has been that people have not questioned things; they’re sort of in this haze where they don’t really think outside of what's been the norm from day to day for the last 28 years. Now, all of the things that have been set in motion because of Emma being in town are forcing people to sort of wake up a little bit at a time and go, "Wait a second, why would she do this?" So, Regina is starting to lose her footing in terms of her hold over everyone in town. There does start to be a little bit of a power shift -- or at least some sort of a power balance -- because once you plant those seeds of doubt then she's definitely not as all powerful as she once was.
The March 25 episode will see Emma kidnapped by the Storybrooke version of the Mad Hatter. What can you reveal about that episode and what he wants from Emma?It was probably the most fun I've had so far shooting episodes. It's one of my favorite scripts. I had such an amazing time. Sebastian Stan, who plays the Mad Hatter, he’s such an extraordinary actor. It was so great coming to work with him every day. He did such cool stuff with his character. I mean, there was not a second I didn't believe he really was this guy. So, from that perspective it was just such a good time.
It does start to plant some interesting seeds in Emma, because it's another person saying to her some of the things that Henry has been saying. She can still justify it away in the sense that, "Well, maybe he read the book. Maybe there's another copy of the book. Maybe he heard about the book." But it is really the first time that there are little chips in Emma's armor in terms of her thinking; not necessarily that there really is a curse and that everybody really is a fairytale, but I think it’s really that turning point for her to realize that there is something very dark and possibly dangerous going on that she needs to try to figure out.
Can you tease anything else about the story lines you're currently filming?I feel like the whole season -- the way I’ve put it metaphorically is -- we’ve been sort of climbing up the roller coaster. It’s been sort of like one notch at a time. Climbing, climbing, climbing, climbing. By the time we get to episode 20, we're hanging at the top. At 21 and 22, we're just flying down. So, all these little pieces of things that have been set up, all these little puzzle pieces that have been planted all along the way for the whole season, a lot happens really fast. All of it starts to come together very quickly. It's going to be a whirlwind at the end. (Full interview)
I like the idea that Emma's presence is causing the haze to lift, though we haven't really seen much evidence of that in recent episodes. I also feel that episode 21 is a bit late in the season for interesting things to start happening. Her description of "climbing up the roller coaster... one notch at a time" is pretty accurate, and I prefer stories that start at the top of the roller coaster. It's nice to know that there are puzzle pieces, though, and that the pace will pick up soon!
I am excited for the Mad Hatter episode! I've been dying for another character to start remembering their fairy tale lives. Life is more interesting when that happens.
