Last week, the Pearson family ventured to Sin City for some pre-Kate (Chrissy Metz) and Toby (Chris Sullivan) wedding festivities. As is usual for This Is Us, the episode took a shocking turn when Randall (Sterling K. Brown) and Beth (Susan Kelechi Watson) returned home to find their former foster daughter Deja (Lyric Ross) living in a car with her mother.

Needless to say, the writers know where they want to take viewers next in the series' penultimate Season 2 episode, "This Big, Amazing, Beautiful Life," and that's into Deja's story.
