Last week proved that as tough as soap diva Erica Kane is, she ultimately met her match on the ballroom floor. Tonight someone else will have to accept defeat (with any luck, as gracefully as Susan Lucci did) when this contest downsizes from five to four contestants. No doubt last night's solo spotlights will influence who is sent packing. — Jennifer Sankowski

Annie has had plenty of attention from the boys since moving to Beverly Hills, but now she'll learn that her flirtatious friendship with Naomi's ex, Ethan, has consequences when Naomi brings yet another guy into Annie's life. That would be Harry's son who was given up for adoption years ago. Being brought to town on the whim of a jealous ex surely isn't the best way to meet one's family, especially when it means crashing your sister's birthday party and making her sweet-16 anything but. — Rhoda Charles
