‘This Is Us’: This Kevin and Cassidy Theory Will Make You Rethink Every Decision in Season 4

As most fans know, This Is Us plays on the ripple effect — the powerful impact that small decisions have on life. But of course, the fourth season isn’t any different. Thus far, viewers watched as Kevin (Just Hartley) chose to stand by Nicky (Griffin Dunne). And by chance, the two Pearsons meet Cassidy (Jennifer Morrison). In recent episodes of This Is Us, Kevin and Cassidy lessened the gap between them. And as a result, fans have been wondering if Cassidy is the mother of Kevin’s child teased in the third season finale. However, it seems the same viewers still don’t think the two broken individuals will be endgame.

[Spoilers for This Is Us Season 4 ahead!]

What happened to Kevin and Cassidy on ‘This Is Us’ Season 4?

At the end of the Oct. 29 episode of This Is Us, entitled “The Club,” the NBC drama confirmed Kevin and Cassidy’s hookup. But, it wasn’t exactly the fairy tale beginning everyone was hoping for down the line — you know, after a few years of sobriety.

In the episode, Cassidy and Kevin get to know each other more at the gym, as the former actor explains why he and Zoe (Melanie Liburd) broke up. And although Cassidy is surprised Kevin wants children, it seems the military officer finally warms up to the Pearson son.

A few scenes later, Cassidy goes to Kevin’s trailer, where she is clearly in shambles after arguing with her husband. Kevin comforts her. And suddenly, Cassidy kisses him. But when she realizes what is happening, she breaks it off, apologizes, and walks out the door.

Then just when viewers think it’s over, This Is Us proves everyone wrong. As it turns out, Kevin stops Cassidy from leaving with another kiss. Later, Cassidy is found naked in Kevin’s bed. And basically, everything is a mess, as they both look remorseful before the episode’s end.

Following “The Club,” This Is Us fans flooded social media to give their take on what happened between the two recovering alcoholics. And it appears most believe the couple’s hookup means Cassidy gets pregnant with Kevin’s child.

“Just curious how many people think Cassidy got pregnant from her night with Kevin?” a Reddit fan pondered. “While I do think anyone is on the table still, the time line fits if she is who they chose to be baby mama.”

In response to the original post, other viewers seem to agree. However, they don’t think Kevin and Cassidy end up together.

“I think she gets pregnant, but ends up reconciling with her husband or spirals out. Kevin takes the baby,” a fan offered.

Meanwhile, some fans suggested that while the couple may not be endgame, they could still raise a child together, without any romantic attachments.

“While I do like Kevin and Cassidy together, I do think it’s possible maybe they don’t get together and just remain friends and co-parents,” a Reddit user wrote. “Such as why we see Kevin’s son in the future scenes….hell we may even see Cass get closer to the family and be there herself.”

“I do think she’s the mother of his child, however, I don’t think they end up together,” another fan explained. “I think she gets back together with the ex-husband and it becomes a huge blended family.”

Elizabeth Berger, Isaac Aptaker, and Jennifer Morrison explain what’s coming next

When speaking with Entertainment Weekly, executive producers Elizabeth Berger and Isaac Aptaker opened up about Kevin and Cassidy moving forward. And of course, the hookup aftermath is going to be messy.

“I think when you tell someone that you’re going to help them fix their marriage and instead you sleep with them, you feel like things went off the rails a bit,” Berger told EW. “So we’re going to see [Kevin] beating himself up a bit for the way this… got away from him.”

Meanwhile, Morrison delved into what’s coming for her character in an interview with People. And as expected, the actress teased Cassidy’s relationship with both her husband and Kevin will become more complicated.

“Obviously, in terms of seeing how all this gets walked out after that [kiss], it’s a whole different thing because you are dealing with repercussions. What does this mean for their friendship? And what does this mean for her marriage ending or not ending?” Morrison said. “What does that mean once he has actually followed through with a physical connection when you’ve already been feeling an emotional connection?”

In all honesty, This Is Us fans may be onto something with their theory about Kevin and Cassidy. The writers have yet to reveal who the mother of Kevin’s child is. And it’s possible the hookup could lead to a surprise pregnancy. However, as Berger, Aptaker, and Morrison revealed, nothing is certain and the whole situation is a bit of a mess. So fans will just have to wait and see how everything plays out.
