Casey and Sam have been going through many make-up break-up phases, meanwhile Derek gets to go to a trip to Sweden if they win a sports game which Sam wins all the points, he only wants to go for the girls. Meanwhile Edwin and Lizzie team up to "observe," spy on teenage behaviour. Edwin finds out that every time Sam breaks up with Casey, Dereks team loses the game, but when they're together they win. So when Sam and Casey break up for good, Derek lies to Casey's best friend Emily, and they work together to help get Casey and Sam back together.
