The episode begins with Operation Mop-up. Marwan managed to slip through the extremely tight security cordon CTU had put up around the Rockland Building. I wouldn't have thought you could slip a knife through that security, but somehow Marwan managed it.
In the meantime, the data gnomes at CTU have been busy. They've already figured out that Marwan is/was an employee at McLennen-Forster (MF), working there under the alias of Harris Barnes. The show oughtta make up its mind how it knows things like this so fast, or at all. An hour ago, at 5:09, CTU magically determined that Marwan used the Barnes alias. Did it take them an hour then to match Barnes up to MF? I know, I know, don't ask questions. The point is to feed info into the plot like little coins in a vending machine.
Jack and Paul are going to head over to MF to look for info on Marwan. Why them? Because they're closest. I wouldn't think that matters in this LA, where everyone is 5 minutes away from everywhere else. And why is Paul going along? Because apparently he helped install a computer system there, and left backdoors that could allow him access.
Now, just that alone oughtta set off all kinds of klaxons in Jack's heroin-addled brain. MF is a defense contractor. Slipping in backdoors that could allow unauthorized access is a beeeeeeeeg no-no. A crime, certainly. But Jack thinks this is just the kind of fellow to bring along when the nation's security is at stake. And no one else. (But then, we have already seen that CTU is woefully undermanned these days.) In addition, just an hour ago Jack was frying Paul's chest with lamp wires as Paul was under suspicion of aiding the terrorists. All Paul did was wonder if there was some info on his laptop. That's all it took to throw Jack off the scent? Paul is no longer under any kind of suspicion? Yeah, let's take Paul along.
The little woman is sent packing back to CTU. But, Audrey feels the need to call Jack en route and ask him to look after her wet fish Brit hubby. Hmmmm. Is Audrey conflicted? It was a nice little scene between Jack and Paul on the drive over, though. Done with just enough honesty and restraint.
Back at Gestapo HQ, Driscoll says good-bye to Maya. A rough road ahead for Driscoll. Edgar asks the question all of America is asking, why weren't the medical staff keeping an eye on Maya. Sarah snaps at Edgar, then trots off to tell Heller about what has happened. Driscoll comes in just at that moment, and Heller dumps the most patronizing oooohhhh, I'm sooo sooo sorry on Driscoll ya ever heard. Ugh.
