*Warning: Spoilers ahead*
In This Is Us season four, episode three, Kate (Chrissy Metz) learns that Toby (Chris Sullivan) has secretly been doing CrossFit over his lunch breaks. Although deep down she knows it’s great that her husband, who suffered a heart attack last season, is taking care of himself for her and their son Jack’s sake, she can’t help but feel angry. The dishonesty, of course, troubles her, but it’s really her own insecurities about her weight that cause the most tension.
When Kate reacts negatively to Toby’s weight loss, he reminds her he needs to maintain a healthy weight, so he doesn’t die from another heart attack. Kate, unfortunately, takes this as an affront about her own weight and suggests that he thinks she might die prematurely because of her overeating. She storms out of the room, but the damage has been done.
Later, Kate apologizes to Toby about her reaction and opts to go on a walk with her neighbor to get the ball moving in the right direction.
