Amanda and Jake plot against David: she'll partner up with David at the dance-a-thon to get closer, paving the way for some leverage to use against him. Too bad it makes Jake explode with jealousy. Let's hope their relationship can survive long enough for a plan to take effect.
Across the dance floor, Liza and Zach are partnered up, which isn't good news for the home-viewing audience (aka Kendall). She calls Liza and gives her a piece of her mind. Kendall better watch herself, given the questions that Liza was raising earlier in the week about the mysterious goings on at Zach's house ... a hollow wall space, Spike saying his mom's living in the wall, etc. Liza's no dummy, and might well be on her way to putting things together.
Madison's reign of terror puts on some tap shoes as she manages to drive Jesse to the point of nearly strangling her AND reinjure Frankie's hands. But when Jesse starts to get suspicious that Madison may have been the one to off North (yes! Thank you, Jesse!), Madison's actions turn downright deadly. Look for someone to get poisoned -- AND someone else's body to end up on the bathroom floor. Dead, perhaps?
