The drama’s aim to play with characters’ timelines is clear in "The Big Three," a reference to Rebecca and Jack’s (Mandy Moore, Milo Ventimiglia) children — who appear to be age eight here, after being born in the preceding series pilot. Randall’s (Sterling K. Brown) concerns about his father (Ron Cephas Jones) differ from Beth’s (Susan Kelechi Watson). Toby (Chris Sullivan) supports Kate’s (Chrissy Metz) efforts to lose weight. Justin Hartley also stars.
