This Is Us Season 2 Episode 18 Quotes

Beth: Man, she's mean.
Randall: I miss Deja classic. No, Deja classic was when we first met her and she was all quiet and sully. I miss Deja 2.0 when she was all used to us and sweet and she told me all my jokes were corny but secretly she liked 'em.

Hope you're enjoying your last day as my fiancee because by this time tomorrow you're going to be my straight-up wife.
