Side note: I try to overlook plot holes in TV shows, but one last night really irked me. While on Alcatraz, they noticed that a BART train under the east bay had stopped. In the time it took the bad guy to unscrew the bottle and hook it into the ventilation system, they managed to get from the island to the mainland, go down into the tunnel through an "emergency hatch," find a vehicle, and drive halfway across the bay. Really? Really? The whole show has kind of been doing the whole "traffic in San Francisco is non-existent" but I've at least been somewhat able to ignore it before now. This completely pulled me out of the moment.
