Well Jon Voight took the pill, and died. No surprises there.
In the next scene, the FBI agents swarm into the building and spread themselves out to search in all the rooms to look for the canister.
They cut to Jack at some base, alone with Tony and some FBI tech guy. Jack gets a phone call from the guy who was interviewing Jack earlier (at the FBI headquarters) about all the events that happened that day (during Season 7

), and said there's an inconsistency in his story. He asked if Tony Almeida's informant regarding the White House attack was really a guy named "Vincent Carter"(?), or whether he mis-heard Tony. Jack says he's pretty sure Tony said the informant's name was 'Vincent Carter' (?).
Before the interviewer asks Jack his next question, the FBI tech guy asked Jack to come and take a look at something. On the screen, they can see the walkie-talkie of every single FBI agent at the scene (in the building). However, they see that the FBI agent who told them that the canister was not inside the building (it was actually Tony Almeida's friend/accomplice)!! He said he was calling from inside the building, which isn't true. He was well outside. Jack then calls Renee Walker to tell her to get all her men out of the building because it's a set-up.
The bomb then goes off.
Miss anymore than that?
