Actress Felicia Day will reprise her role from the unaired (at least in the U.S.) episode of “Dollhouse,” “Epitaph 1” when the series bows early next year.

“They wrap up the storyline in an amazing way and I’m blown away by the writing,” Day says of the Season 2 finale. Like its predecessor Epitaph 1, the sequel is a modern zombie tale set in the future. “I play Mag. She’s part of group of renegades who find their way into the Dollhouse and relive some of the steps of how society degenerated because of the Dollhouse technology. The episode is crazy and wonderful and it’s just so much fun working with such great people.”

Day went on to tell TV Guide that the cast’s saying good-bye to the sophomore seires hasn’t been easy.

“Obviously people are sad. Acting that the end of the day is a job that you put a little bit of your heart into,” she says. “But they know they’ve made a lot of great episodes and I can’t wait to see what everybody does next.”

“Dollhouse” airs Fridays on Fox.
