Babes in bondage?

Zombie mind control?

Season two of Dollhouse will take this drama to entirely new levels, as the show's stars explain below.

Heating up: Tahmoh Penikett and Eliza Dushku both confirm that Echo and Ballard will grow tighter this fall. As Dushku told E! News:

"Echo doesn't know entirely what's going on yet... [but] as she becomes more and more self-aware, she's recognizing this constant, tall, dark, looming man in the Dollhouse."

Penikett added: "They have a connection. It's not a physical attraction, but I hope it's something that we explore a lot more this season. You're not quite sure what it is. There's a past, there's a history, there's an understanding between them that's very different. I think the audience is really going to like it and be really curious about where we're going in the first few episodes."

More Dollhouse romance: Said Enver Gjokaj: "Sierra and Victor are definitely still involved. They're going to explore that relationship more. They explore the Sierra-and-Victor love as dolls, but then also they're going to go into the backstory of both of them."

Murder, sex and more: Fran Kranz (Topher) tells fans to sit back and hold on tightly. The reason? Season two if full of "sexually dark stuff... murder... sex and murder."

Count us in! Dollhouse premieres on September 25 with an episode titled "Vows."
