‘This Is Us’: Did Kate and Toby Confirm This Theory About the Future? The Winter Premiere Needs to Come Back ASAP

[Spoilers for This Is Us Season 4 ahead!] The This Is Us Season 4 fall finale was filled with one devastating hit after another. The NBC drama teased fans about what’s to come when it returns for the winter premiere on Jan. 14, 2020. But as promised, This Is Us began answering a few questions in regards to the future flash-forward, including what happened to Kate (Chrissy Metz) and Toby (Chris Sullivan). For the past few seasons, This Is Us fans have been wondering if Kate and Toby get a divorce — possibly because of cheating or an affair. And now, it looks like viewers might be on to something.

What happened to Kate and Toby in the ‘This Is Us’ Season 4 fall finale?

For those of you who don’t remember the third season finale of This Is Us, and older version of Toby appeared without a wedding ring. Meanwhile, Kate is nowhere to be found and Toby is alone as he visits the Pearson family for Rebecca (Mandy Moore).

Then in the This Is Us Season 4 fall finale, titled “So Long, Marianne,” Kate and Toby continue to struggle with one another. Toby gets upset at Kate for lying about baby Jack’s first solid food, which he experienced at Gregory’s (Timothy Omundson) house. Kate then reveals she is frustrated with CrossFit Toby and is hurt he left her behind on their weightloss journey.

Later, both Kate and Toby appear to get back in the groove with one another, just in time for Thanksgiving. Kate is about to tell Toby how she really feels. But she then quickly changes her mind. And then it happened.

Towards the end of the episode, Kate accidentally reads a text message on Toby’s cellphone. “Trying to get past it, but it’s hard,” Toby wrote in a group text to the CrossFit crew. Then someone known as “Lady Kryptonite” in the chat, messaged back. “Don’t let her bring you down. Here for you,” the message says.

And to make matters even worse, in a flash-forward sequence nine months in the future, This Is Us showed Kate signing a sheet of paper. But she signed her name “Kate Pearson,” with no “Damon” anywhere to be seen.

Fans previously theorize Toby cheated on Kate and it leads to their divorce in ‘This Is Us’

Following the third season finale, This Is Us fans predicted Kate and Toby’s divorce. A fan on Reddit wrote:

So we see Toby always wearing his wedding ring, right? And as I was rewatching the last episode of the 3rd season, right at the ending when they’re meeting at Kevin’s future place, I noticed they don’t actually mention Kate. Toby just says he spoke with Jack and “they’re” coming. What I also noticed is that Toby isn’t wearing a wedding ring in the future. It’s only for a couple of frames but still. So I assume they’re either divorced or Kate’s no longer alive.

Meanwhile, other fans wondered if Kate would have an affair with their neighbor, Gregory. And others hypothesized Toby would cheat on Kate. But some also pointed out that Toby was cheated on by his ex. So it seems unlikely he would do the same, given “the depressive episode that triggered for him nearly caused him to kill himself.”

Now, with Toby’s group text message and Kate signing her name without “Damon,” fans are wondering if the theory is coming true.

“99.9% SURE I CALLED IT,” one fan wrote on Twitter. “Toby cheats on Kate with someone from the gym.. Which is why he doesn’t have on his ring in a previous flash forward & also Kate signed her last name Pearson in tonight’s finale!!”

Nevertheless, Toby and Kate could still be splitting up, even if there isn’t an affair involved. Or perhaps it’s all simply a red-herring. However, fans will just have to wait and see what happens next.

What the ‘This Is Us’ producers say about what’s coming for Kate and Toby

After the This Is Us Season 4 fall finale ended on NBC, producer Isaac Aptaker opened up about what’s coming for Kate and Toby during an interview with Entertainment Weekly. And it seems like fans will go on a journey to find out who Lady Kryptonite really is.

“When we come back in January, we’re going to right away deal with the aftermath of Kate discovering LadyKryptonite5 and trying to figure out what the hell that’s all about and who this woman is,” Aptaker said.

Meanwhile, the producer confirmed the Kate and Toby storyline will continue in the This Is Us Season 4 winter premiere on Jan. 14. Aptaker told Glamour:

I think we’re going to be dealing with the immediate fallout from that text message right when we come back in our next episode. I mean, that’s an upsetting and scary moment for a wife to find out that her husband is not only venting and complaining about her and their marriage to a group of friends, but that there’s some mysterious woman responding and giving him counsel and marital advice. What Kate does with that troubling information is something we’re going to be addressing right away when we’re back in January.
