Apparently the Hendersons looked in on Kim while Jack was away being dead.

At the hospital, they detect the bad guy in the basement. How did he get down there?! They said they had that sealed off. Was that the purpose of the electrical conduit information? Just how big is this conduit? Did Viktor slide down it into the basement carrying this ginormous gurney and the gas cylinder? My head hurts.

Curtis orders Team B to set up a soft perimeter. Does CTU ever set up any other kind?

They all go a-creeping through the basement, and find the baddie. Curtis shoots him. Whatever happened to aiming for the legs or something so the guy stays alive and you can interrogate him for crucial information? Curtis orders his team to search the body.

They find the canister. Curtis says it is armed. (The krazy kaptions say it is "on".)

CTU wants a mandatory evacuation of the downtown core. Oh that is going to go smoothly.

Buckaroo arrives home and Jack clonks him. Jack has Henderson handcuff himself behind the back? I'm trying to figure how that's done. Is that even possible?

Jack now wants Buckaroo to give up what he knows about the gas. Henderson says he can't do that. Jack points the gun at Henderson's knee, and Henderson says yeah, just like I taught you, Jack. (Ah, a nod to the beginning of last season, when Jack shot that Turkish terrorist in the knee to get him to talk.)

Gracious! Jack shoots Miriam in the leg! Cold, Jack. Look, I know she didn't give you the password you wanted, but she's been sitting quietly on the couch like you asked. Did you have to shoot the poor woman?

Peter Weller's reaction is some good acting. Can you imagine, say, Keanu Reeves' reaction? "You shot my wife. Whoa." But, Henderson still isn't talking. He says he can't.

So, Jack orders to prep an interrogation room with hypocine-pentothal. Goody! We're finally to get some torture on this show! About time.

A guard comes up to Jack and shows him the red digital readout device they found on the dead guy. Oh great work guy. Curtis told you to search him ten minutes ago! It took you this long to find the thing?

The gas is about to be released, so Curtis does his Ben Him act, grabs the canisters, jumps in his chariot and goes weaving through the hospital and crowds and tosses the canisters in a containment device just in time. Hooray! The hospital is saved. I wonder what the Medicare charge code is for that sort of thing.

As the episode comes to a close, a terrorist has Twisted Sister and Boyfriend on their knees, and he shoots them both in the back of the head. Cold.
