When Shaylen fears failing her dance exam, she enlists a dance tutor, who turns out to be Santiago, the Tango Master also the alter ego of Andrew. Through his unconventional methods of dance (some even involving crunchy peanut butter on shoes), Andrew as Santiago elevates Shaylen's performance even though she does not think so. On the day of the exam, almost settles for an incomplete when her partner trips on his cape and is injured. Andrew steps up, dons his Santiago alter ego, and encourages Shaylen not to settle for anything less than an A. They dance and their performance is excellent. Shaylen, surprised at herself, passes the test. Andrew and Shaylen almost have a romantic moment when Andrew burps up a chorizo and Shaylen is quickly brought back to reality and friendship. Meanwhile, Sarah uses her video game (Sherlock Bones) and deductive powers to single out and catch the person who's been stealing the recipes to her dad's latest creations: Salad on a Stick and the Muffnut!
