In the May 3 episode, Chuck braves himself to ask Sarah for the next level of their relationship but she declines the offer.
Chuck asks Sarah the idea of moving in together and she says "Why would you do that?". In the next episode of "Chuck", Chuck and Sarah are assigned to train under Craig and Laura Turner (guest stars Fred Willard and Swoosie Kurtz), a married CIA team who, despite their impeccable record, hate one another.
The Turners' stormy relationship forces Chuck and Sarah to wonder if they're doomed with the same fate. Meanwhile, Casey must train the newest member of the team - Morgan. "Chuck Versus the Role Models" airs May 3 on NBC.
Last week, NBC released another promo for the episode, paying tribute to classic TV series "Hart to Hart". Chuck stood in as Jonathan Hart while Sarah posed as his wife Jennifer.
