Okay...time to get your groove on people.
Let's examine where we are and try and figure out where we're headed, shall we?
* Is Audrey in the clear? No need to remind readers here of Nina Meyers who was fingered half-way through Season I only to wiggle out of it by falsifying some records. There are still a lot of clues pointing to the Department of Defense as a hotbed of traitorous activity.
* Is the Department of Homeland Security part of the plot? Miles as a mole is too obvious but that doesn't clear DHS completely.
* Did anyone else wonder why Bierko needed "schematics and access codes" for a target where he needed an employee of the gas company to help him release the gas? After offing the guard, the terrorists used a key to open the door so they didn't need access codes for that. And schematics? Bierko had to ask the gas company employee to take him to the control room. In short, where is the next attack going to be?
* WTF is Sherry's problem?
* Finally, will Diane and her son reappear at some extremely inappropriate time in the near future just in time to get kidnapped or placed in mortal danger so that Jack has to leave Audrey in order to save them?
