Post Description

Jack and the rest of CTU take action to protect the remaining isolated areas while Chloe wrestles with her grief over Edgar's death. The fact that a corrosive agent had been added to the nerve gas means that it is slowly eating away at the seals of the isolated safe-rooms and forces them to take immediate action to slow it down so that Curtis can arrive with a Haz-Mat team. Lynn McGill sacrifices himself to shut down the controls of the ventilation system, allowing Chloe to override and slow down the pathogen, saving the lives of the survivors. Meanwhile Tony contemplates revenge on Henderson. Martha bolsters Logan's judgment as he faces political pressure from Gardner about imposing martial law. As Tony prepares to kill Henderson with a lethal injection, he hesitates and Henderson, waking up, plunges the needle into Tony, killing him.
