Green Harvey faced death when John Crichton was attacked by Ka D'Argo in Luxan hyper-rage. John's reasons to live (Earth, dad, pizza, sex, cold beer, fast cars, sex, Aeryn, love) were not adequate so Harvey proposed revenge. To discover a reason to live, Crichton created a cartoon reality to oppose an illusory D'Argo. To combat him, Pilot proposed to run from him, Jool proposed to try to talk to him, Chiana proposed to fight him. All failed. Crichton went with Harvey's idea after being clinically dead for a time and it worked. But Crichton's idea, love, worked best. After that, Harvey unlocked Noranti's subliminal message: "Aeryn is pregnant". Crichton got the message after Aeryn left and at once decided to retrieve her. Unfortunately, after that, Moya was sucked down by a wormhole, leaving Crichton stranded. After Crichton returned to the ship, Scorpius asked for asylum. Harvey suggested killing him. Scorpius proposed to erase Harvey. Since this Harvey had been in Crichton far longer than his twin, Crichton hesitated, but eventually agreed. Harvey was removed. After Crichton and Scorpius had allied and Crichton broke the agreement and left the hybrid to die, Harvey was "resurrected" and improved to Harvey 2.0. He was loyal to Scorpius and had a connection with him so Scorpius would know he was alive. After Scorpius was rescued thanks to Harvey's lies, a war between Scarrans and Peacekeepers broke out and Crichton finally created the wormhole weapon. Harvey was deleted after his success, since his purpose was finally fulfilled. His last words were: "Goodbye John. Thanks... for your memories"
