"Stu", as Stewie's future self is called, tells Stewie that he is on vacation (Stu explains that rather than just simply travel to different places in the world, people from his time travel to other time periods). Stu reveals he cannot tell anyone about his time and leaves for his time, Stewie stows away with him. Stewie learns he will not become ruler of the world but rather "a 35-year-old Parade magazine-reading virgin". Stu passes off Stewie as a Nicaraguan boy named Pablo to everyone until Stu can send him back to his own time. Stewie learns he will work at the Quahog Circuit Shack while living with Rupert, his childhood teddy bear, in a filthy apartment. Disgusted with the way his life will turn out, Stewie remodels Stu's apartment and gets him to lose his virginity to his co-worker, Fran (though he spends more time crying than having sex). The next day, Fran tells everyone about the humiliating experience, costing Stu his job for having relations with a co-worker. Returning home, he finds that his apartment is in flames due to the stress-relieving candles Stewie put there.
His life now ruined, Stu laments the day of his near-death experience at the community pool, revealing that memories of the experience will re-surface when Stewie is 20 years old, causing him to repress most of his major emotions and preventing him from taking any risks. They visit Lois (who reveals that she had recognized "Pablo" as her "little Stewie" immediately) at a retirement home for a loan and get a new time travel watch. Stewie travels back in time to the day of the accident and prevents himself from getting crushed by the chair. However, future Stewie gets vaporized by present Stewie, thus creating a paradox and skipping the formalities of Future Stewie disappearing eventually. As the family packs up and heads for home, Meg bids farewell to a boy to whom she's been talking to, considering how much she likes his name: Ron.
