|“||Clever beats strong any day.||”|
Leo is trapped by Marcus at school, but escapes and follows Marcus to his house. He gets photographic evidence that not only proves that Marcus is evil, but that he also wants the Lab Rats. Unfortunately, he is captured by Marcus' robot. Leo escapes by out-thinking Marcus with a move Chase used to beat Adam at arm wrestling (which is being clever). When Leo tries to bust Marcus, his phone is destroyed by the broken teleporter. Marcus' house appears normal except for a camera that Donald suspiciously notices, but doesn't mention. Marcus' dad reveals himself and says that Marcus has failed him and he will take care of Donald and the Lab Rats. Meanwhile, the Lab Rats try out a teleporter, but accidentally teleport Tasha to Fresno and must fix the teleporter (one of Davenport's inventions) to bring her back.
