BioShock
Eventually, after completing tasks like saving an artificial forest from dying and helping an insane artist build his sculpture, Jack confronts Ryan in his office, who is playing golf. Ryan reveals a truth that he has pieced together. He is Ryan's illegitimate son by an affair with Jasmine Jolene, a dancer.  When Jolene became pregnant with Jack, she, in desperate need of money, had her embryo surgically removed and sold it to the highest bidder. She had not realized it was Frank Fontaine who purchased the son, leading to her death by an angry Ryan. Ryan further reveals that, after purchasing Jack's embryo, Fontaine made him to obey orders when he is told "Would you kindly..." Jack was then sent to the surface when the war started to put him beyond Ryan's reach. When the conflict between Fontaine and Ryan reached a stalemate, Jack was sent instructions to board a flight with a package and to use its contents, a revolver, to hijack and crash the plane near the lighthouse, enabling him to return to Rapture as a tool of Fontaine. Because Jack was Ryan's son, he could freely use Rapture's bathysphere network, which had been locked out to everyone except those within Ryan's "genetic ballpark". Finally, Ryan has Jack kill him, wanting to die on his own terms. With Ryan's death, Jack realizes too late that Atlas has also been using the trigger phrase to control him. Atlas reveals himself as Fontaine, who faked his death to throw Ryan off his trail and take control of the city, leaving Jack at the mercy of the reactivated security systems. Dr. Tenenbaum and her Little Sisters help Jack escape through the vent system, where he falls and loses consciousness.
