As we've seen plenty of times before, nobody knows more about internal building structures in LA than CTU. They have already matched the schematic off the dead guy to Tyler Memorial Hospital in Westwood. There was also a time indicated on the schematic, so CTU thinks another gas attack is imminent.

And so we helpfully cut to the hospital where a baddie is in hospital whites, pushing a gas cylinder-laden gurney around.

So, another good point to stop and ask just what was the original plan here? Did the baddies have these hospital whites and fake photo id all ready to go for this guy? When did they get ahold of these hospital schematics, showing the air ventilation system? Was all this thrown together immediately after Anton and his Merry Men were killed at the airport?

The clocks are at :29 to :27 as Jack sneaks up to House Henderson. In the split screen as we return from commercial break, in the Terrorist HQ they are looking at a fancy colored graphic of the hospital schematics. Again, was this graphic quickly created in the last few hours? This is the most amazing backup plan in the history of backup plans.

Jack goes into the house and pulls a gun on Miriam, wanting to know where Buckaroo is.

Martha has a tender moment with Aaron, says thank you for saving her life, and takes his hand. Mike comes in, and apparently thinking that no human being ever touches another human being's hand unless they are adulterous floozies, hisses at Aaron to make sure nothing never doesn't not happen again for the first time. Or something like that.

The hospital is trying to evacuate everybody. Not an easy task with sick people. Hospital Security Guy says they can't move some newborns. CTU asks if other hospitals can help, but apparently all neonatal transport units are in use. Really? Are there so many babies in LA that need transporting in special units, day in and day out?

Viktor phones in and warns Sgt Bierko that the hospital is being cleared. Sgt. Bierko says he must finish the mission, even if it mean Viktor dies a horrible foamy nose bleedy mouth death. Viktor agrees. He knew the risks when he signed up with Team Terrorist. He's not sure how he can get down to the basement though. Bierko consults their professionally done slapped together at the last minute graphic, and mentions an electrical conduit.

The Russkies have given CTU intelligence indicating that Sgt Bierko is probably behind the terrorist attacks. Nice of them to give that up now, and not back during the airport fiasco. Logan again chimes in with the obvious and blathers on about the need to do something.

Chloe is looking through Henderson's "wiped" computer and says there is bill paying software and downloaded music. So what exactly was wiped?? Gaahh! Chloe does find a hidden partition, and it contains a password encrypted file. Miriam doesn't know the password. Or isn't saying.
