(Spoiler alert!) On the season finale of Tuesday night, Kevin and Madison may not have had a wedding but, in the final moments of the episode, which flashed five years into the future, someone else, who literally no one was expecting, did.
Early in the episode, Toby revealed to Kate that he finally got a job offer. The kicker was that the job was based in San Francisco. Ultimately, Kate remembered that she made a wedding vow to Toby that she would care about what he needs more than what she needs for the rest of her life. Kate called her co-worker a.k.a. "The music teacher," to resign from her position. However, Philip would not accept her resignation, because she was simply too good at her job.
Later, Toby told Kate he would turn down the job offer but, ultimately, the two decided to double down on their love for each other and commit to a long distance relationship. Everything seemed fine on the Kate and Toby front, until the classic plot twist ending.
Kevin is seen entering the bride's room prior to the ceremony to get clearance on a movie quote in his wedding speech, and it is Kate who steps out in a wedding dress. "This is the last time I'm doing this, so go crazy, brother," Kate tells Kevin.
Next door, the music teacher a.k.a. Philip a.k.a. the new Miguel is exiting his room as Kevin tells him, "Hey, listen, uh, you're okay if I do some British jokes at your expense, right?"
Fans' jaws dropped after finding out that, in the future, Kate and Toby aren't together anymore and, instead, Kate is getting remarried to the music teacher. So, once again, This Is Us flipped the script on fans and left us totally hanging until the next season, which will also be the final one.
