If this episode weren't filmed before the show was officially canceled, I'd actually think there would be a chance the dirty bomb would go off -- as some sort of crazy ass swan song or something -- but it wasn't, so it won't. Jack will defeat Tarin and Samir just in time and we'll hopefully get to watch an old-fashioned Jack Bauer chain-choking, throat-ripping terrorist beatdown of at least one of them (probably Tarin; Samir is for the finale, of course). And hey, maybe Dana will get murdered too! We've got two hours, and you don't need a dirty bomb detonation for there to be bloodshed, after all.

24 airs on Fox tonight from 8 PM to 10 PM, opposite a new Gossip Girl, Dancing With the Stars and Chuck. And Life Unexpected and Trauma as well, sure, if you're maverick enough to consider those shows.
