It’s the cameo you never thought you’d see.
An older version of Jack Pearson (Milo Ventimiglia) is seen in a new preview for This Is Us’s upcoming season finale exchanging words wife Rebecca (Mandy Moore).
New photos from the episode – which is titled The Wedding – depict scenes from the buildup to Kate’s (Chrissy Metz) nuptials to Toby (Chris Sullivan), with her family – consisting of Randall (Sterling K. Brown), Kevin (Justin Hartley) and Beth (Susan Kelechi Watson) – pitching in to help.
