Warning: Spoilers ahead for That ’90s Show season 2!

Before Seth Green reprised his role as Mitch Miller in That ’90s Show, he played one of Eric Forman’s enemies in That ’70s Show. Despite being set over 15 years after the original show ended, plenty of familiar faces have made their way over to the sequel series. With Eric and Donna’s daughter Leia serving as the central figure among That ’90s Show‘s cast, it makes sense for original characters linked to the Formans and Pinciottis to reappear in Point Place. Tommy Chong’s Leo is always a highlight, but That ’90s Show season 2’s cameo list also featured Green’s return.

By the time Seth Green appeared in That ’70s Show season 5 in 2003, he had been acting for nearly two decades. Rather than just appearing in a quick cameo role, Green’s character acquired a recurring role that lasted into season 6, serving as one of Eric’s pesky antagonists. Their dislike for one another became one of the show’s funniest gags throughout That ’70s Show seasons 5 and 6, but that feud actually spilled over into That ’90s Show.

Eric & Mitch’s Feud In That ’70s Show Seasons 5 & 6 Explained

Eric & Mitch Got Off To A Rocky Start

In total, Seth Green’s Mitch appeared in five episodes within seasons 5 and 6, resulting in the actor becoming one of That ’70s Show’s best celebrity cameos. His debut came in “The Battle of Evermore,” which saw Eric and Red competing against Mitch and his father in a Paul Bunyan-inspired competition. The seemingly harmless father-son events turned into a serious rivalry between the Formans and Millers, creating the feud that would last for the next 20 years.

In truth, Eric and Mitch had several chances to patch things up between them in That ’70s Show. Mitch may have played a newspaper prank on Fez and Kelso in season 5’s “Nobody’s Fault But Mine,” but his relationship with Eric and the group took a positive turn in season 6’s “Substitute.” After Eric hit Mitch with a golf ball, he invited Green’s character to hang out with the crew, who eventually accepted him being around. In fact, Eric and Mitch briefly bonded over shared hobbies. That friendship was short-lived, however, thanks to Mitch’s interest in Donna.

Mitch’s return toward the end of That ’70s Show season 6 involved the character creating a wedge within Eric and Donna’s relationship. The plan to break up the couple stemmed from Mitch’s crush on Donna, reigniting his feud with Eric, which would only get worse in Green’s final That ’70s Show appearance a few episodes later before coming to a surprising conclusion.

What Happened During Mitch’s Final That ’70s Show Appearance

Mitch’s Master Plan Backfired

Season 6’s “5:15” marked Seth Green’s last appearance as Mitch in That ’70s Show. Donna accompanied Mitch to his brother’s wedding, which happened to take place at the restaurant where Eric worked. During Mitch’s Best Man speech, he foolishly claimed Donna was his fiancée, angering both Donna and Eric. To finally end their feud and war over Donna, Mitch proposed a fight with Eric. Much to the relief of both characters, they worked out a deal that involved Mitch giving Eric his “G.I. Jacques” doll in exchange for no fighting.

That ’90s Show Gives Seth Green’s Mitch A Sad Fate After That ’70s Show

Mitch Never Got Over Donna

Despite not appearing in That ’70s Show‘s final two seasons, Netflix’s sequel show didn’t forget the Seth Green character. Green returned as Mitch in That ’90s Show season 2’s “Just a Friend,” where he was revealed to be the manager at the local mall’s Hot Topic store. To spend more time with Gwen, Leia decided to get a job there for the summer. When Mitch learned of Leia’s last name, he instantly questioned her connection to Eric, something Leia cleverly denied. However, Mitch’s That ’70s Show fate got darker despite being hilariously fitting.

Not only did Mitch imply that he was still obsessed with Donna over 15 years after the events of That ’70s Show, but it was clear that he was still stuck in his high school feud with Eric. He also believed that Eric stole Donna from him, showing that he hadn’t moved on from the crush. Mitch’s That ’90s Show fate got even sadder when it was shown that he was feuding with teens who worked at Abercrombie & Fitch. Once he learned Leia’s parents were really Eric and Donna, the Hot Topic adventure came to an end, but it would likely remain Mitch’s future.
