On last week's episode of Dollhouse, Alpha finally showed his face...  and it belonged former Firefly star Alan Tudyk.

In an interview with Entertainment Weekly, Tudyk previews the May 8 season finale of Dollhouse.

What can you tell me about next week's finale?
Tudyk: Everything that Alpha has done has been about Echo. He's obsessed with this woman. And next week you find out what his plans are for her, and why he's obsessed with her.

Will Alpha's other personalities emerge?
Tudyk: Yes. I think he has 43 of them. Tim Minear wrote and directed the next episode, and he outdid himself. It's classic Tim Minear.
