Synopsis
Floating helplessly above Earth, to his relief John gets a com from Moya. D'Argo, Aeryn, Chiana and Rygel follow his signal through the wormhole and pick him up, but a radio broadcast reveals that they have arrived in the mid-1980s - over a decade too early.
Arriving back at his family home, John soon realises how his presence has upset the timeline when he discovers that his father is due to fly on the Challenger - just before the space shuttle disaster. He must prevent this or history will be changed.
The aliens hide out in an abandoned house while John tries to persuade his teenage self to prevent his dad from leaving. Meanwhile, Chiana slips out to have some fun, and a neighbour calls the police after seeing Rygel. Only Noranti's hallucinogenic dust prevents the officer who arrives from taking action.
John, realising that his dad will not be persuaded, decides to kidnap his younger self and fake an accident so that his father will have to rescue him and will not leave on Challenger. Noranti brews up a concoction that will put young-John into a coma. John goes to pick up his earlier self from a favourite spot. Chiana appears and knocks out young-John's girlfriend, promising to deal with young-John if old-John looks after the girlfriend.
Returning to the house, Chiana keeps young-John occupied whilst Noranti finishes her coma-juice by taking his virginity. As young-John drinks the coma-juice, the police arrive once more, and are knocked out by Aeryn and D'Argo. Young-John has a bad reaction to Noranti's medicine, and stops breathing, causing old-John to become invisible.
Young-John is brought back from the brink by Noranti, but old-John remains ghostly, and sets off to convince his father to come and rescue young-John. He tells his mother where to find his younger self - as she runs off in panic, he becomes solid once more. Back at the house, D'Argo sets charges to make it look as if there's a fire.
Jack Crichton arrives, runs into the smoking house, but knocks himself out once inside. D'Argo and John rescue him and young-John. Mission accomplished, John and the aliens leave. Out in space, they follow Pilot's signal through the wormhole back to their own time, and land safely on Moya. On board, John finds a welcome party - four humans, including his dad. Unnerved, he pulls a gun on them and asks his dad - "Was it a bass, or a trout?"
