Fans of the NBC series will recall that the Season 4 finale introduced the character, played by Josh Hamilton, as Madison’s obstetrician when she realized she was pregnant with Kevin’s twins.

In a call with reporters after that episode, Fogelman said the doctor would become “an important character” in Season 5 as parenthood approached for Kevin and Madison.

The executive producer added: “It’s no coincidence he was introduced in the same episode that Dr. K returned.”

Alas, we’ll never know whether This Is Us‘ Dr. Mason offered the kind of homespun wisdom for which Dr. K was famous;

after the COVID-19 pandemic altered production in 2020 and beyond, Hamilton never appeared on the show again.

But the character served his major purpose, Fogelman told reporters in a conference call Tuesday. “The intent of that episode had been that [Mason’s young daughter, Sadie] and Mason,

the advice they gave to Madison that led her to go have an honest conversation with Justin [Hartley]’s character, Kevin, and led to them co-raising and co-parenting twins and changing his life,” he said.
