On "American Horror Story: Coven," the notorious bad witch Madison, played by Emma Roberts, is not one to take things lightly. Read: coming back from the dead, initiating the season's first threesome, and gunning for the role of Supreme. But despite her sideways smirks and vengeful antics, Madison has started to show a more insightful and deeply wounded side that's beginning to balance her extremes. Yahoo TV spoke with Roberts by phone and got the scoop on just how far both she and Madison are willing to take it — which is to say, all the way and then some. Roberts clued us in about her major nerves working alongside Jessica Lange, embracing her personal obsession with witches, and being up for anything that comes Madison's way this season.

Whether she's delivering killer one-liners ("Most people never get over stuff like that, and I was like, 'Let's go to Jamba Juice!'") or scheming her way to the top, it's certain that we've only scratched the surface of the coven's lead bitchy-witch.

Do you think Madison has a master plan behind her manipulative actions?

Well, I think her master plan is kind of what everyone wants, to be the Supreme. Madison especially wants it, and I think that will become more and more apparent as the season goes on. I think she'll do whatever it takes, let's just put it that way.

You said on Twitter that last week's episode, "The Dead," was one of your favorites this season. What scenes were the most memorable for you?

In last week's episode, there were so many memorable scenes, but the threesome scene was definitely the hardest scene to shoot. There was also an intense sex scene that I had with Spalding that got cut. That experience in itself was really crazy and definitely hard to shoot. So there were a few tricky scenes.

What is it like working alongside a legendary actress like Jessica Lange?

When we're working together I find myself staring at her, and I have to tell myself to stop staring! (Laughs) It's not even just the way she talks; it's her whole being and her presence on the set. The way she delivers her scenes is so beautiful.

The most intimidating scene was when Jessica slit my throat. It was still the beginning of the season, and I didn't really know her that well. I was really nervous because I didn't want to forget my lines or mess up because I admire her so much. I was so nervous that day! Overall, that scene was the most difficult yet most fun scene to do.

In "The Dead," Madison gives a really intense monologue about being a millennial, and it is the first time we've seen Madison be so introspective. Do you think coming back to life was a turning point for Madison?

What I love about Madison is that every episode you kind of see different sides of her. Sometimes she might be a bitch and she might have her issues, but I don't think she's a bitch to her core. I think she's smart and has had a lot of stuff happen to her. She definitely has her horrible moments, but she's not a complete idiot or a--hole. She's growing.

Is there anything that Madison has done or will do this season that scares you out personally?

Not really. Actually, it's more shocking to read what the writers come up with every week. I get my script and it's just crazy, and I'm like, "Where do you guys get this stuff?" I would never come up with that stuff. It's so crazy.

You've mentioned in interviews that you have a personal obsession with witches. What are some of your favorite witchy TV shows?

I loved "Witches of Eastwick" and "Sabrina, the Teenage Witch." I also love "The Craft," which I definitely watched a bunch recently. I don't know why we're so fascinated with witches, but I'm obsessed! I never really got into the vampire craze, but I've always been obsessed with witches.

Have you been embracing some of the more Goth styles from the show off set?

Oh yeah! Since we're shooting in New Orleans, every vintage store I go into I'm like, "Do you have anything that's like "The Craft?" (Laughs) And people always look at me like I'm so weird. I've gotten a lot of cool long, black dresses and boots. Every time Taissa Farmiga and I get dressed in the morning, we check each other out and we're like, "I want that, I want that, I want that." We're all obsessed with the wardrobe on the show. All of us love it.

This is your first season on "Horror Story." Are you ready and willing to come back for more?

Of course! I would love to! I'm so grateful to be on the show, and I'd love to come back as a different character — maybe a good girl next time. (Laughs)
