In This Is Us Season 6 Episode 4, “Don’t Let Me Keep You,” Jack’s mom, Marilyn (Laura Niemi), dies. So he drives to her home in Ohio, and he meets Debby at the home. Jack calls her “Cousin Debby,” but she quickly corrects him. Debby is Marilyn’s cousin, not his. Nevertheless, the name sticks.

This Is Us fans also learn that Jack’s mom moved in with Debby after leaving Stanley (Peter Onorati). It’s also clear that Debby and Marilyn were very close until the very end. Debby arranged Marilyn’s funeral, and she wrote a poem in her cousin’s honor.

Meanwhile, Debby doesn’t seem to be a big fan of Jack at first. She points out that it took him 13 years to visit, which weighs on Jack throughout the episode. But even so, Debby appears touched by Jack’s eulogy in which the Pearson patriarch thanks Marilyn’s friends for giving her a new home.
