You've got to admit that this season is not on par with the prior two. With that in mind, here's my summary of Day 3:
Let's start with the President. He has a girlfriend. But they broke up because her ex-husband committed suicide. He also has a brother, Wayne, who is his chief advisor. Wayne had an affair with Zoë from Firefly (she was also married to Dozer), but now she' s married to some rich guy. If we're lucky, the President will get back together with his ex-wife!
Jack is a drug addict, and he has a girlfriend. She's dead now, but he doesn't know that yet. He's also getting back together with his old girlfriend, the one who killed his wife.
Back at CTU, Tony is now married to Michelle. But they're having a lover's spat because she's trying to get him fired from his job (for no apparent reason).
We also have Chloe, some weird secretary/analyst who's hiding her baby under the desk. Is this great action or what!
And how could we forget about Kim. She's dating Chase, who was recently captured and tortured. Funny thing is, she doesn't seem to care. I guess now that no person (or animal) is trying to kill, attack, or eat her, she's all calm and collected. Plus, she's got her career as a computer genius to think about!
So that's about it. I may have left out some other minor stuff about drug lords, jail breaks, and deadly viruses. But that part of the plot is all boring and the writers have kept it to a minimum.
