Is Sophie the Mother of Kevin's Son on This Is Us?

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 seem to go their separate ways after their coffee date, the show's creator Dan Fogelman 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."

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

The guessing game really never ends on This Is Us. After giving us some answers about Rebecca in the flash-forward, the season three finale opens a whole new can of worms with the revelation that Kevin is now a dad. As Randall sits in the kitchen with Beth and adult Tess, a mini Kevin can be seen walking around the house looking at his phone. While the young boy tells "uncle Randall" that his dad stepped out to get takeout for everyone, there is no mention or sight of his mother.

However, in the season four midseason finale, we learn that Kevin is engaged as he celebrates his 40th birthday. Meaning that Kevin just might be married in the flash-forward. Naturally, we have a whole lot of questions about this new "her" mystery. Does Kevin get back together with one of his past loves or is the mother of his child someone new like the recently introduced veteran Cassidy? Let's break it down.
