The last time viewers checked in with Kate, at the mid-season premiere, Toby had just admitted a marriage-ending level confession. Not of cheating, or of emotional unfaithfulness, but his internalized ableism against his son, Baby Jack. Kate is heartbroken, especially since her gift to Toby for his birthday was or the three of them to go on a retreat where they can connect and learn from other parents of blind children, and learn how to help their son.

The episode ended on a note of hope, as Toby connected with Jack when his son finally distinguished light and shadow for the first time. But the series has already hinted this was a short-lived respite. When Kevin gets back from the funeral at the end of "A Hell of a Week" Part 2," Madison is over at Kate's house, dogsitting the family pooch while everyone is gone.

But when Kevin asks where everyone is, she offhandedly says Kate and Jack are at the retreat. Toby is "at work." Perhaps something unavoidable came up? But even so, his non-attendance at something so important for his son's future well-being suggests Kate isn't kidding when she tells her brothers this marriage is hanging by a thread.

This Is Us next airs on Tuesday, Feb. 11, 2020.
