Uncovering the New "Her" Mystery on This Is Us: Who Is Kevin's Fiancée in the Flash-Forward?

OK, the most obvious choice here is that Kevin and Sophie get back together (again) and start a family. Though Sophie tells Kevin she is engaged to someone else when they meet up in NYC during season three, it's clear that they still have chemistry. They were each other's first loves! While the two go their separate ways after their coffee date, Kevin eventually returns home to comfort Sophie when her mother dies. As they reminisce about the past, it's clear that they still have a spark.

The show's creator Dan Fogelman also made it seem like their story isn't over quite yet. "I think there's more to explore there between the two of them," Fogelman told Glamour. As for whether she'll appear in season four, he teased, "You never know. It depends on what happens."
