Caroline Dupree served as one of Fez's (Wilmer Valderrama) girlfriends on That '70s Show, but the character's fate was left unknown. Actress Allison Munn portrayed Caroline for a total of nine episodes of the Fox sitcom from 2001 to 2006. Based on her alarming behavior, she was known as "Crazy Caroline" to Fez's close group of friends. Here's what happened to Caroline, including what Munn believed happened to her character after the final breakup with Fez.
Caroline was first introduced in That '70s Show season 3 with the episode titled "Fez Gets the Girl." Fez saw Caroline, who he considered "one of the most beautiful girls in the world," but he never had much luck with the ladies. On the flip side, Caroline was also too nervous to talk to Fez, but Donna (Laura Prepon) stepped in and set the pair up on a date. A few episodes later, Fez and Caroline started dating, but then her true personality started to show. After a few outbursts of anger, especially upon learning that Fez once kissed Jackie (Mila Kunis), Fez decided to break up with Caroline. When she started stalking him, Fez decided to pretend he was dating Donna, which made his ex even more unhinged.
Munn's character finally let go of Fez before disappearing for nearly five years. Caroline returned in That '70s Show's eighth and final season, revealing she was as insane as ever. Her reunion with her ex officially came in "Stone Cold Crazy" when Fez realized he still had feelings despite their complicated past. At the time, Fez lived with Jackie so he had to hide the fact he was living with another woman. When Jackie revealed her feelings for her roommate, Fez ended his relationship with Caroline for good. The character wasn't seen again, but Munn came up with a theory regarding the fate of Caroline.
In a recent interview with PopCulture, Munn shared that she would be happy to revisit some of her past characters, including Caroline. She also imagined that Caroline would have never fully given up on Fez, stating "I think Caroline would have doubled down on her affection and her love for him" before adding that "love never dies." That was basically Munn's kind way of saying that Caroline's obsessive behavior would have distracted the character from ever moving on.
Considering Caroline once passed out from strangling herself at the notion of Fez breaking up with her, it would be safe to say that she never fully moved on. If Fez and Jackie did end up together well after That '70s Show came to an end, Caroline was probably still lurking around somewhere. It was unclear if she remained in Point Place after the final breakup, but either way, she probably would have followed Fez to the ends of the earth.
