NUP_176703_3399.JPGSibling rivalry is a normal thing in most families; between the twins and an adopted triplet, the Pearson family on This Is Us is able to take it to a whole new level. Though there’s clearly plenty of love between the Pearson kids, there’s also plenty of tension. It’s those realistic, complex kinds of relationships that have helped the NBC series become such a big hit. The actors love those relationships just as much as the fans — Justin Hartley told us he’s especially intrigued by the dynamic between his character, Kevin, and Sterling K. Brown’s Randall. (Click on the media bar below to hear Justin Harley)
