Not really a spoiler ... I put Enver Gjokaj on google alert because I love him so and got this from an interview with one of the co-writers (Maurissa Tancharoen)of "Epitaph One."

And Enver [Gjokaj] – he's outstanding! There's so much that can be done with him!
Absolutely! The way you're all excited about him? That's exactly how we feel. We're going to milk him to death in season two. Why wouldn't we? Enver is a chameleon, and so talented.

Can you give me any tidbits on what's in store for him in season two?
We may do something where we explore where he came from, and how he came to be in the Dollhouse. The fun thing about him is we can do anything with him. The possibilities are endless.
