Fever

S2, E4: Elizabeth catches a bad cold from Verity. With a raging temperature, her power to hyper-function and use her genius is out of control. She finds herself acting against her will, fulfilling other peoples' wishes - a cold cream for Verity, sunglasses which give Russ scientific formulae and an exo-skeleton for Garth, transforming him into an armored warrior Garthdor. The illness worsens and Elizabeth, close to death, calls for the only person who can save her - Toby. He hyperfunctions just in time to save Elizabeth's life, and although she takes it as a sign he cares about her, Toby is still firmly focused on Nikki. Meanwhile Russ and Sacha have to deal with an out of control Garth in the Surf Cafe and only just prevent Jack from seeing more wicked science in action. But he sees enough to suspect the two trios have access to something special and he wants 'in'.
