Where to See the Cast of This Is Us After the Series Ends "Instantaneously, Bear's existence has taught me lessons about surrendering to the current moment and shown me where in my life I have selfish tendencies and self-centered tendencies," the actor said of becoming a parent. "Bear constantly brings me back to the current moment, which is ... perfect in every way. And I think that's a good reminder." As the series finale of This Is Us looms around the corner, many of the show's cast members are sharing some of their final moments on set of the award-winning drama that's captured the hearts of millions across the country.
