Question: Wait, didn't you say that last week's Heroes was Thomas Dekker's last (Ask Ausiello 1/24)? Either he's got a doppelganger, or that was him in Monday's episode.
Answer: Did I say that was his last episode? What I meant to say was that he recently filmed his last episode. (You wanna try doin' this job? Do you?! Didn't think so.)
