The Truth Is Out There

S2, E17: Jack films the lead-up to an inter-school Science Expo as an excuse to find wicked science and hopefully blackmail Elizabeth and Toby into making him a genius too. When Elizabeth hears Sacha's exhibit is a secret, she invents a truth serum and forces Russ to spill the beans. She teleports Sacha's invention to the lab so she can sabotage it, not realizing she's also teleported Jack. Once alone in the Lab he steals the truth serum, escapes and confronts Elizabeth, using the serum on her. Jack demands she tells him how she became a genius! She is just about to blow the secret, when Toby tackles him to the floor. Jack gets sprayed with the serum and is about to reveal his knowledge of wicked science to the whole school when Toby, using Elizabeth's re-wiring, blows up Sacha's exhibit. It's a narrow escape for Toby and Elizabeth as Jack is left completely humiliated, though determined not to give up.
