The cast of This Is Us stepped out in style for the AFI Awards luncheon in LA on Friday, but one very important person was missing in action: Sterling K. Brown. The actor – who made headlines this week when it was announced that he’d be joining the cast of the much-anticipated Black Panther movie – was nowhere to be seen, though his onscreen parents Mandy Moore and Milo Ventimiglia , sister Chrissy Metz, and wife Susan Kelechi Watson held down the fort and posed together for photos both on the red carpet and inside the event.
