Another fun episode of "spy-on-spy" tonight, with a heckuva cliff-hanger, and yes, I was peeved that the hour was up! So I guess I was involved in the episode. Anyhow, Sidney's dad covered up most of the "Kate Jones" tracks, and nuked Will's news story on it when none of his facts checked out, but Will found a "bug" in "Kate Jones"'s car when she had it repaired by one of Will's mechanic friends and since she was killed by SD-6, her car left Will the "bug" clue. So Will will probably wind up close to death as he keep pushing for more clues to who "Kate Jones" is, and will probably figure out that Sidney is some sort of agent (when he puts her travel schedule into the mix). It's pretty cool how everything that Sidney brings back home to SD-6 actually builds into a larger puzzle. Sidney probably didn't pass her lie detector test (if you believe the previews), but it may be some mis-direction to keep us even closer to the edge of our seats. Re: Sidney's mom's book: I'm now convinced that Sidney's mom was the KGB agent that she keeps acusing her dad of being. It must have been really painful for Jack Bristow to allow his wife be "retired" with his knowledge.
