6 Big Spoilers from 'This Is Us' Season 4 Mid-Season Finale

Kate and Toby

Kate and Toby are likely going to have marriage issues after she discovers a text message on his phone at Thanksgiving. She expressed her feelings on his weight loss and he told his CrossFit friends, “Trying to get past it, but it’s hard.” A friend named LadyKryptonite responded, “Don’t let her bring you down. Here for you.”

When we flash forward to nine months in the future, Toby is not with Kate at her 40th birthday party.
