the end of Season 7, Kelso drives Jackie to Chicago after her break-up with Hyde. When Hyde follows her there to propose, he finds Kelso naked, wrapped in a towel, making a comment implying that he and Jackie were about to have sex. Although Kelso frequently makes sexual comments to every female on the show, including Jackie and Donna, Hyde believes the two really were about to engage in sex, and drives off to Las Vegas, effectively ending his relationship with Jackie. Ashton Kutcher did not renew his contract for the eighth and final season of the series but he appeared in a recurring guest role in the first four episodes of season 8 in order to bring closure to the character.

This causes Kelso to wonder what he has going for him and decides that Jackie is the one for him all along. He decides to propose to Jackie, seeing as she was the one he has always loved. He later rethinks this decision, deciding against it after a job offer is given to him. However, Fez had already told Jackie about his plans. Feeling pressured to do something, and scared that he might lose all his future chances with Jackie, he attempts to propose, albeit with a balloon (which is how Jackie wants to be proposed to), at the Forman's anniversary, but Jackie says no, much to Kelso's relief.

He then joins his friends for one final circle before his departure. Kelso does not appear in succeeding episodes, although he is occasionally referenced by the remaining characters. He returns, though, in the series finale to welcome in the
