Jonathan "Jack" Donahue Bristow was the father of Sydney Bristow and a fellow double agent for the CIA at SD-6. He assisted his daughter in bringing down the criminal organization and assisted the CIA at their base of operations in Los Angeles thereafter. He was recruited to APO, a black ops division of the CIA, by former superior at SD-6 Arvin Sloane, who ultimately betrayed the U.S. government in pursuit of the findings of Milo Rambaldi. Jack was left in charge of APO after this.

In a final effort to stop Sloane, Jack sacrificed his own life to trap an immortalized Sloane in a cave for the rest of eternity.

Family

Early life

SD-6

Jack kept his affiliation with SD-6 a secret from Sydney, who also worked there. His cover was that he worked in supplying airplane parts. Jack was one of the few people working at SD-6 who knew its true allegiance; that it was a branch of the Alliance of Twelve, and he was working with the real CIA against SD-6 (Truth Be Told).

Shortly before Season 1, Daniel Hecht called Jack to ask for his daughter's hand in marriage. Jack was shocked that Daniel would ask as he clearly did not know his daughter very well, but accepted (Truth Be Told).

Working as a CIA mole in SD-6

Season 1

Jack was informed that Sydney had told Danny that she worked for SD-6, and so he was tasked with killing Danny to prevent a leak of information regarding their agency. After Danny's death, Sydney attended the funeral and Jack observed from his car. He then found out that Sydney was being targeted by Sloane because she was a potential threat and managed to save her from some attacking agents. He explained that he also worked for SD-6, and said that SD-6 was part of the Alliance of Twelve, a criminal organization, and not the CIA as she had been led to believe. He tried to get to Switzerland, but she refused and ran away. He later went and told her that her request to be a double agent for the CIA had been approved, and informed her that he was also one working against SD-6 (Truth Be Told).

Sydney met with her father at SD-6, who said that it would facilitate their plan if Sloane knew that she knew that Jack worked at SD-6. Sydney asked if he knew that they were going to kill Danny. He said that he did, and she slapped him. Sydney told him never to speak to her again, then left. He later told her that he booked a flight for Danny to go to Singapore but he arrived too late; he had already been killed. Jack told Sloane that Sydney had gone away for a few days, when in fact she had gone to get a nuclear weapon back that SD-6 had sold to terrorists (So It Begins).

1x03Jack

Jack refuses to answer Sydney's questions about her mother (Parity)

Sydney approached Jack unannounced and asked him about the many questions she had regarding the past. However, Jack was reluctant to answer and irritated that she had approached him unheralded. Later, Marshall was unable to open a locked case containing a rare Rambaldi sketch, and so Jack was called in to assist. Jack contacted K-Directorate, who was in possession of the key that opened the case, and offered to meet at a neutral location and the two agencies to open the box together. Sydney dismissed the idea but Sloane said that K-Directorate did not know that there was another half to the code that SD-6 already had, so they had nothing to lose by showing the enemy this half. Sloane left and Sydney asked Jack one more time; did her mother know that he was with the CIA? He said that she did, and there was no secrets between the two of them. However, Sloane later asked Jack if he told Sydney the truth about her mother's death, and Jack shook his head (Parity).

421Dance

Jack dances with who he believes to be Irina Derevko (Search And Rescue)

18 months before Season 4, at the British Embassy in Vienna, Jack was sent to kill Irina Derevko. He asked to meet with her privately, and told her that she had broken his heart. She brushed it off, saying "that was another lifetime. I won't do it again." They kissed, and Irina tried to leave. Jack refused to let her, asking what it was like to order a hit on her own daughter. Irina said that he was not supposed to find out, and Jack shot her, dead. Little did he realise that it was, in fact, a doppelgänger that he had shot and the real Irina was still alive (Search And Rescue).

Season 4

Jack learnt that Marcus Dixon thought he saw Irina Derevko alive when he was shot by Elena, her sister. Sydney assured him that Dixon must be wrong, but Jack was less sure. When Sydney reminded him that it was Jack who shot Irina, he said that they have seen doubles before, citing the Helix Project. Sydney said it seemed too convenient that the only person who could stop Elena was being dangled in front of them, but Jack thought her refusal to accept the idea suggested fear. He said that they had to pursue every lead (Search And Rescue).

They used Lucian Nisard who informed them that Irina was alive and Jack had murdered a duplicate. Jack told Nadia that Irina was alive, and that she was in Guatemala. The two met Sydney in Tikal, Guatemala to find Irina. Jack waited downstream as Sydney and Nadia broke through Elena's guards to get to their mother. She was escorted back to the CIA, but arrested upon her return to the States. Sydney managed to talk Director Chase into releasing her to help stop Elena, who had constructed a huge Mueller device over a city in Russia that was sending the citizens mad. Jack gave Irina her deal; once she helped stop the device, she would return for life in prison. She accepted, and Jack told her that not a day went by that he did not regret "killing" her (Search And Rescue).

Season 5

Relationships

Laura Bristow (aka Irina Derevko)

Jack fully believed Derevko's cover as Laura Bristow, his wife. He told her about his job with the CIA, which is not recommended for agents. When the APO team tricked Jack into believing he was in 1981 during the later stages of his radiation poisoning, Jack confessed his deep love for her (Mirage).

Sydney Bristow

Although Jack did not give Sydney the greatest childhood, he was deeply protective and proud of her. He worked hard for the CIA but regretted missing important events in her life, such as her birthday. He even went so far as to decide to leave the CIA so he would be around more for her childhood (Mirage).
