Day 7: 11:00 p.m. – 12:00 a.m.
The Hazmat technicians start examining Bauer. Almeida is brought to Starkwood, where Hodges orders his men to torture the former for information. Bauer is revealed to have been exposed to a non-infectious pathogen that causes mutation and eventually death. The FBI obtains evidence that Starkwood was using Sangalan population to test the pathogen as the result of a deal made with Juma. Moss reinstates Walker now that she is revealed to have been right to aid Bauer. Greg Seaton, Hodges’ assistant, frees Almeida, claiming an intention to stop Hodges in exchange for immunity, which Allison signs. Seaton takes Almeida and FBI agents led by Moss, who has omitted Bauer because of his condition, to a compound, which they find empty. Starkwood mercenaries surround the FBI and demand them to leave. Seaton is revealed to be still loyal to Hodges and freeing Almeida. Meanwhile, Allison appoints Olivia as the Chief of Staff. The latter convinces Pierce, who has been retired, to stay with her until the crisis is over.
