As if the threat of a tsunami isn’t bad enough, the potential for it to hit a nuclear facility raises the tension even higher in the new episode "Wave Goodbye." Walter (Elyes Gabel) and his colleagues do what they can to alter the course of nature — and if that seems impossible, never count Team Scorpion out. Toby (Eddie Kaye Thomas) tries to help his former fiancee Amy (guest star Shantel VanSanten) recover her identity without Happy (Jadyn Wong) finding out. Katharine McPhee and Robert Patrick also star.
