Put down that peanut butter, Julia - the leading lady's allergic! As the first paying audience gets to see Rebecca DuVall's "unique" take on Marilyn, Dev attempts to deal with the guilt of cheating on Karen by taking every possible opportunity to meet up with his mistress. And as Uma Thurman's contract expires with one whole episode left in the season, the ever important question is back on everyone's minds; who's going to play Marilyn next? Back in the real world, Olly gets nerdier than ever with the SMASH trivia, and he and Ali debate organized religion vs the male anatomy.
