Giving more insight into the Kelso family dynamic, Casey’s role continued the family’s reputation as heartbreakers who were quick to move on from girlfriend to girlfriend. However, while Kitty and Red enjoyed Casey because of his charm and military history, Eric couldn’t stand him, seeing through his lies to Donna and correctly predicting that their romance would end in him getting bored and her getting hurt.
Wilson’s character hasn’t been forgotten, as Donna recalls dating Casey Kelso in That ‘90s Show part 1.

After Casey and Donna break up inThat ‘70s Showseason 4’s ending, Luke Wilson’s character is phased out of the sitcom asDonna and Eric’s relationship resumes.

That ’70s Show’s Returning OG Kelso Makes A Confusing That ’90s Show Plot Hole Worse
The return of Michael Kelso’s daughter, Betsy, in That ’90s Show part 3 continues a plot hole issue that was established in the sequel series' debut.
What Happened The Last Time Casey Kelso Appeared In That ’70s Show
Casey Is Eric’s Gym Teacher During Summer School
Casey Kelso’s final appearance is inThat ‘70s Showseason 7, episode 21, “2120 So. Michigan Ave.” The episode is primarily centered on Eric deciding that he wants to become a teacher, but needing to take a summer gym class in order to officially graduate from high school – despite having graduated a “year” prior inThat ‘70s Showseason 5. When he arrives for class,Eric finds that his gym teacher is none other than Casey Kelso, who he still resents from his relationship with Donna.
However,Michael Kelso’s brotherstill acts “friendly” to Eric while condescendingly calling him “Foreplay,” and even tells Eric he’ll pass the class if he successfully completes one pull-up. When Eric fails,Casey offers to let Eric pass if Donna goes on a date with him, which he happily agrees to despite angering Donna. Of course, Donna’s anger leads to Eric returning to the gym and successfully performing his single pull-up, thus passing the class while saying goodbye to Luke Wilson’s character for the last time inThat ‘70s Show.

What Happened To Betsy Kelso After That ’70s Show
Michael Kelso’s daughter Betsy is officially back in That ’90s Show part 3, and her story with Jay & Nate proves she’s lived up to the Kelso name.
Casey’s last line to Eric was, “Wow, that’s really cold, Forman… I’m just gonna go sign your transcript cause, um… I don’t think I wanna hang out anymore, okay?” It was a classic Casey way to leave his character, but the notion that he was still hanging around Point Place and living out his glory days of being the former football team quarterback left room for him to potentially return in the future. While Casey didn’t appear inThat ‘70s Showseason 8, hecould make his Point Place return inThat ‘90s Showpart 4 alongside his nephew, Jay.

That ’90s Show Part 3’s Ending Already Teased A Great Return For Casey Kelso
The Return To Point Place High Is Perfect For Casey’s Re-Introduction
That ‘90s Showhas already laid the groundwork for Luke Wilson to reprise his role as Casey Kelso in Netflix’s hit sequel series. WhileThat ‘90s Showpart 4 hasn’t been confirmed by Netflix, it’s likely that the sitcom will step up the cameos with more returns from iconic characters related to the new Point Place teens. It’s clear that most people from Point Place either return home or never leave, andCasey Kelso seems to be among the group of residents who would still be living there in the ‘90safter coming home in the ‘70s.
To tie Casey’s story intoThat ‘90s Show, the Netflix seriescould reveal that he’s still working as Point Place High School’s gym teacher. BeforeThat ‘90s Showpart 3’s ending, Donna even gave Leia her old Point Place High gym shirt as a symbol that she would let her stay in town. If Leia ends up attending Point Place High School, it wouldn’t be surprising to see her have Casey Kelso as her gym teacher, which would likely result in Casey insulting Eric while asking about Donna and wanting to see her again – much like Mitch Miller’s return.

With Leia potentially moving to Point Place inThat ’90s Showpart 4, the sitcom could follow the teens throughout the fall while school is in session and football is in season.
Asimilar way to bring Casey Kelso back forThat ‘90s Showwould be for him to become one of Point Place High School’s football coaches.That ‘90s Showpart 1 revealed that Nate is on the football team, so part 4 could actually show him attending practices and having Casey coach him. Considering Casey called himself “the best quarterback that Point Place High ever had,” he’d likely be eager to return to his heyday inThat ’90s Show. If so, it’s possible that Jay Kelso would end up joining the team under his uncle’s leadership as well.
