The Season 5 cast of Alias. L to R: Marshall Flinkman (Kevin Weisman), Marcus Dixon (Carl Lumbly), Thomas Grace (Balthazar Getty), Jack Bristow (Victor Garber), Sydney Bristow (Jennifer Garner), Renée Rienne (Élodie Bouchez), Arvin Sloane (Ron Rifkin) and Rachel Gibson (Rachel Nichols)

Season 5 of Alias aired from September 29 2005 to May 22, 2006. Between December 2005 and April 2006, the series went on hiatus due to Jennifer Garner's real-life pregnancy as well as news of the show's cancellation. Season 5 consisted of 17 episodes, including four double-length episodes, two aired back-to-back upon its return from hiatus, and another two aired back-to-back for the series finale.


As Season 5 begins, Vaughn is abducted. Sydney learns that Vaughn is under suspicion of being a double agent and that the crash may have been a cover for his extraction. Vaughn later escapes and explains to Sydney that his real name is André Michaux. He reveals that he is investigating a secret operation known as Prophet Five, which at one point involved his father. During a mission in recovering a Prophet 5 book, Sydney receives a phone call from her doctor with some untimely news - she's pregnant (a development created to deal with the actress' real-life pregnancy). Vaughn is later shot, and apparently killed, on orders of Prophet Five operative Gordon Dean (Prophet 5). Four months later, as Sydney continues to investigate Vaughn's murder, she works with an assassin and associate of his, Renée Rienne, in order to unearth the inner workings of Prophet Five, while at the same time trailing Dean and his criminal organization "The Shed," disguised as a black ops CIA division, very much like SD-6.

Two new members are added to APO to replace Weiss, who moved to Washington, D.C. for a new job, and Nadia, who is still in a coma. Thomas Grace is a brash young agent with unorthodox methods who often butts heads with Sydney (...1...). Rachel Gibson is a computer specialist who, like Sydney, was deceived into thinking she was working for the real CIA and briefly works as a mole within The Shed, as did Sydney within SD-6, before The Shed's destruction by Dean (The Shed).

In an ongoing subplot, Arvin Sloane follows his own personal obsession, finding a cure for Nadia. Sloane is jailed for his actions during Season 4; however, he is released after the sentencing committee is manipulated by Dean. In exchange for his freedom, Sloane is now working for Dean as a mole within APO (Out Of The Box). Unaware of Sloane's new allegiance, Jack agrees to let Sloane rejoin APO and use its resources to seek a cure for his daughter.

With the series' end, it emerges that Sloane's ultimate goal is that of immortality, for which he sacrifices Nadia's life. However, he is trapped forever in Rambaldi's tomb by a critically wounded Jack, who sacrifices himself to avenge all the pain Sloane caused Sydney over the years. Sydney tracks Sark and the Horizon to Hong Kong, finding Irina. After a final battle between them, Irina plunges to her death (All The Time In The World).

The series ends with a flash forward to several years in the future. Sydney and Vaughn are semi-retired and married, with a second child named Jack in honour of Sydney's father. Daughter Isabelle exhibits the same ability to complete the CIA test that marked Sydney's inborn skills to be an ideal agent at that age. However after completing the puzzle she casually knocks it over, perhaps signalling that she will not follow in her mother's footsteps (All The Time In The World).


It took place in 2005 and 2006.


Similar in style to the last season, each episode compromises of the team being given an objective and having to complete it, overcoming any obstacles that come along in the way. It is not until the series end, when APO is destroyed and Sydney goes on a quest to stop Sloane once and for all that the format is slightly altered.
