If you've been wondering when we'd see more of the post-apocalyptic world that Joss Whedon granted us a glimpse of in the unaired Dollhouse season one finale, "Epitaph One," wonder no longer. Apparently the series finale — which, God willing, will air in January — is called "Epitaph Two: The Return," and features Felicia Day's character. The episode is from the pen of "Epitaph One" writers Maurissa Tancharoen and Jed Whedon, plus Andrew Chambliss. Don't forget to watch two hours of Dollhouse — featuring Summer Glau — this Friday at 8. [Mo Ryan on Twitter]
