This Is Us shared a behind-the-scenes moment from the set of the January 12 episode, where Sterling K. Brown and his co-star Angela Gibbs were seen in character as son and mother, Randall and Laurel. The pic was apparently snapped shortly after Randall let out a cathartic scream and released the demons from his past in the episode titled Birth Mother.
In the Instagram pic, as seen below, the actors were in a pool which was used to represent a river that ran behind a home owned by Laurel s Aunt Mae. It was a place where Laurel went to reflect and release any feelings of fear or sadness she had experienced in her life.
