Tom is regaling Sam's family with a story of a gentleman wearing a lady's corset on stage, and they all seem politely amused, except maybe for Sam's dad, Ronald, who begins cataloging his disappointment with his son's choice of profession (because it's not stable, not because it's for nancy boys). Sam's mom protests to Tom that their family loves theater, but Tom says he agrees with Sam's dad, that dancing is a risky profession. Ronald says he likes Tom.
Rebecca is grooming herself in front of her Marilyn shrine (because everyone has one) when Derek knocks and comes into the dressing room. He tucks his head right over her shoulder and does more of his movie-star whispering, saying that Marilyn was luminous, like Rebecca, and this is all so ridiculous I can't believe it's working. He begins rubbing her shoulders and is being both sleazy and condescending, and then he kisses her and they fall to the floor together, and what -- what -- someone please tell me this is a hallucination. I will not stand for this, Commodore Norrington!
Tom offers to help Ronald with the dishes, because someone raised him right. Ronald asks what the worst thing he's ever seen happen to a dancer is, and Tom starts cataloging bad knees, bad backs, getting too old and how dancers generally don't get pensions, and Ronald asks Tom to talk some sense into Sam, which Sam of course overhears. He is not pleased.
Outside the theater, Ivy is has come to look for Derek and Ellis has fetched the Neti Pot he was sent for, and they realize they've been had. Look, I'm not objecting so much to Derek throwing Ivy over for Rebecca, but it's been done so poorly. He told Ivy he loved her, what, yesterday? This is sudden and unprovoked and just badly plotted. Everything else in this show has happened at the pace of glaciers moving, but in the space of one episode, maybe two, Rebecca and Derek go from hating each other to banging on her dressing room floor? And it wasn't even the typical Moonlighting,"I hate you but actually I can't stop thinking about how your hair smells dammit I love you!" Outside the dressing room, Randall stops Ivy and Ellis, and they can hear Derek and Rebecca talking and laughing inside the dressing room. Ivy leaves, devastated, and I hotly anticipate her vicious revenge.
