Among all of the tragedy and heartache on This Is Us, Kate and Toby, or "Katoby," if you will, have always been a shining beacon of light and hope. But after it became clear they aren’t together in any of the flash-forwards, fans have begun to question if Kate and Toby get divorced on This Is Us. It would be just another heartbreaking plot twist for fans to deal with in the coming episodes or seasons but, sadly, that seems to be the case.
Chris Sullivan, who plays Toby on This Is Us, told The New York Post after Season 3 ended that Kate and Toby aren’t together in the future. He confirmed that in the flash-forward where Toby is seen in bed without a wedding band, "Kate and Toby are no longer married." Chris admitted that anything could trigger their split, even if they seem to be doing (mostly) fine in present day.
But do Kate and Toby divorce on This Is Us?
Chris added that anything could happen between Kate and Toby to lead to their split, but it seems to be divorce rather than Kate unexpectedly dying in the future. This Is Us has already painted a grim future where Rebecca is seemingly on her deathbed, so it’s unlikely that the future would also see Kate dying or dead herself. Thanks to Chris's not so subtle hints at what’s to come, it seems as though Kate and Toby do divorce at some point.
This theory about Kate and Toby points to infidelity.
One This Is Us fan on reddit wrote that they believe Kate will have an affair, which will lead to their divorce. The fan pointed out how Kate has already hid one thing from Toby when the neighbor, Gregory, fed their son an avocado while Toby missed out on the milestone. They wrote that it might be the first of many lies Kate tells Toby which leads to her eventual infidelity with the neighbor.
Another fan on reddit theorized that even if Kate doesn't physically have an affair with the neighbor, it could be an emotional affair. Viewers have already seen how much Toby works and how much time he spends at the gym, which both equate to less and less time spent at home. This has enabled Kate to seek friendship in their neighbor, who has now taken a liking to Jack. It’s possible that Kate’s relationship, or even friendship, with the neighbor, is what leads to her divorce from Toby.
Kate’s future on This Is Us looks uncertain.
Kate is the only main character who hasn’t yet been mentioned in the flash-forward scenes on This Is Us. Toby was shown heading over to Kevin’s house with sidewalk chalk for whatever reason. Randall and an adult Tess left her place of work to meet Beth at the house too. And although Kevin hasn't yet been shown in the future, it’s clear that everyone is gathered in his home where his son lives.
Toby also alerted the family that he "just talked to Jack" and "they’re on their way" in one of the flash-forward scenes. He could have been referring to his adult son Jack and his girlfriend, who were both introduced in the Season 4 premiere. Or, he could have been referring to Jack and Kate. But Kate still hasn't yet been mentioned by name or shown in any of the flash-forwards on This Is Us.
There's the possibility that Kate will be shown in the next flash-forward, but for now, her future is unclear. Regardless of where Kate is in the future, however, the one thing fans can be sure of is that she and Toby are no more, as heartbreaking as that may be.
