Andrea Barber defends Full House sequel series was greenlit, most of the original cast were confirmed to appear - except for the youngest Tanner sister. Over the years, fans hoped that somehow, she'll show up in any capacity, but even as the series wrapped up, Michelle is still nowhere to be seen.
Played alternately by John Stamos, were open about their attempts to convince the sisters to partake in the project, but with no luck. Apparently, while Ashley didn't have any intention of returning in front of the camera, Mary-Kate briefly considered the gig but ultimately ed on it.
Instead of mulling over Michelle's absence, Fuller House opted to use it as the butt of several jokes in its five-year-run. The final one was delivered by DJ (Candace Cameron-Bure), and Stephanie (Jodie Sweetin) rummage through their old stuff in the house's attic for their weddings' "something old" and "something borrowed." Kimmy spots Michelle’s bike and asks her friends when they’re going to get rid of it because, if their sister hadn't picked it up yet, she wasn't coming while looking straight to the camera. It's a meta-comment, telling viewers to not get their hopes up about Michelle showing up. It drew laughs, but not everyone is exactly thrilled with these jabs. Nevertheless, Barber defends them in a recent interview with TV Line:
“Michelle gets at least one little poke per season, so we had to do it one last time. It’s not meant to be mean, obviously. It’s all good-natured, in good spirits. We poke fun at everybody.”
Danny (Bob Saget) even making a comment about Kimmy taking over her spot as his third daughter. The Netflix series didn't provide an explanation of why Michelle's not coming to her sisters' wedding - in fact, she's not even mentioned in the final season except for that final Kimmy jab, which is obviously disappointing for loyal fans.
Granted that there's slim to no chance of the Olsens boarding Fuller House, the Netflix series could've found other ways to incorporate Michelle other than making fun of her. Out of its five seasons, she's only mentioned a handful of times, and most cases, it was simply to make a meta-comment about the twins refusing to reprise the role. If anything, they could've at least been more proactive in factoring her in the final season - perhaps she takes care of her sisters' wedding dresses since she's a fashion designer. They could've staged a call where she apologetically informs them that she can't be home on DJ and Stephanie's wedding day.
