Bauer's day gets off to a shocking start when former colleague Tony Almeida (played by Carlos Bernard), last seen in Day 5, returns after being left for dead by a terrorist conspirator in CTU's infirmary.This is not the hugest news, of course, because: a) It’s long been known that the original plan was to bring Tony back in the final seconds of season six; and b) Tony’s death didn’t mute the ticking clock the way chubby CTU computer geek Edgar Stiles’ death did in the prior episode.
