About me: Jack is the Illegitimate son of Andrew Ryan and Jasmine Jolene. When she discovered she was pregnant, Jolene sold the embryo to Brigid Tenenbaum and Yi Suchong. Jack underwent genetic modification, growing him up much faster than a normal child. Jack weighed 56 pounds and had the "gross musculature of a fit 19 year old by the age of 1". Jack's genetics would allow him to use bathyspheres, be resurrected at Vita-Chambers, and the automated security systems would not be as effective against anyone with Ryan DNA.
Sometime in 1958 before Fontaine faked his death, Jack was sent to the surface in a bathysphere as a sleeper agent to live out a normal life until he would be activated with the command phrase "would you kindly". This caused Jack to board a plane in 1960 that would pass over Rapture's entrance. He would hijack the plane and force it to crash, giving him access to Rapture to carry out his mission.
Unexpectedly, however, Jack would rebel against his programming, and kill both Fontaine and Ryan, and save as many of Rapture's little sisters as possible, bringing them to the surface world. He would later become a florist in Paris, while still suffering from the trauma and madness that Rapture had caused him.
