Bolt from the Blue

S2, E13: Elizabeth is driven wild with jealousy when Toby and Nikki decide to go to the school dance together. She invents a lightning generator, producing a fork of pure lightning which pursues Nikki. In fact, it does a right-hand turn frightening Nikki so much that Elizabeth is able to blackmail Toby into taking her to the dance. An unlikely pairing of Russ and hockey player Peta provides comic relief, but Jack manages to steal the lightning controller from Verity. He uses it to force Elizabeth to tell him everything about wicked science and wrecks the entire dance with a barrage of lightning bolts. Elizabeth has to neutralize the potential threat that Jack now poses and has to watch a reconciled Nikki and Toby enjoy their first kiss.
