He got a new phone when he was holding Lauren hostage and asks Nina to get him a car. The new phone was in the car, and with it being a CTU phone everyone in CTU will have access to his new number.

The photographer made out with Mandy (not her friend). Mandy blew up the plane killing the photographer. The shooter went through extensive plastic surgery to look like the photographer so he can get through security with the Pass that Mandy stole from the photographer on the plane.

| 4. if the real alan york is dead and nenia is working for who ever why tell jack that allan york is dead. |
Two possible reasons, one: Nina doesn't know everything about Gaines' plans. She was working for the Drazens, not Gaines. Two: if she didn't tell him it could have exposed her as a traitor.
