Jack discovered that Alan Morgan, the man he met when posing as Alexis Drazen, had been paid to turn off a section of the power grid that affected an area in Saugus. After driving to the area with George Mason, Jack discovered that the location was a wildlife preserve.

Jack Bauer discovered an underground detention facility in Saugus and found out that a high security prisoner was being transferred to the facility at the same time that the power had been scheduled to be turned off.
