The security guard misses his respond time. George Mason isn't sure if this guard is dead, but he decides not to take chances. He immediately places CTU on lockdown from the interrogation room. This prevents the would be terrorist from escaping. He knows he has less than five minutes before the cannister releases the nerve gas, killing them all. Chloe looks through security footage, she sees the assasin murder this guard and gives Bauer an image to search for. The assasin attempts to take another guard hostage, and force him to open the gates. This guard realizes his own life is in danger, cooperating with this terrorist might be his only chance to survive. But he cannot bring himself to leave his friends to die. He sends Mason a signal that nerve gas is about to be released. The terrorist murders the guard for this. Jack immediately shows up and kills the terrorist. Chloe sees the security footage of the ventilation system, just as the cannister begins releasing the gas. The system cannot be shut down remotely. Acting quickly Chloe begins isolating what rooms she can. Four rooms are isolated. One of which is the interrogation room with George Mason and Mandy. The main conference room s isolated. Jack and others make it there just in time. This room has Audrey, Teri, Nadia, and Chloe among others. But most of CTU does not make it to safety in time. One woman begs to be let in, but that would release nerve gas into the room and kill them all. Jack tells her to go to another room. He knows it's futile, but he can't bring herself to tell her it's hopeless. She falls over and dies a painful death before she can even make it out of the room. Many others die all over CTU. Then Jack sees something horrifying to him. Tony Almeida, outside. He was suppossed to be out searching for Gaines. Tony must have gotten back just as... Without the protection of these rooms, Tony Almeida begins convulsing and dies, while Jack helplessly watches.
