Scorpion is nearly to normal with the regular roster after Tim's departure, only Paige is upset about how jealously Walter handled that. Cabe is moving out of Happy's home and gives her his mother's heirloom brooch for her wedding with Toby The team's routine mission at the Federal Pumping Station in Redwood, California in the desert turns into their hardest case when they are forced to freeze Cabe's body in order to save his life after he is seriously wounded by a copper shard that snapped off from the force of the turbine's friction, too far to wait for a helicopter. The team must collect various materials, forcing Sly and Happy to face their fears -even a rattle snake- and Paige and Walter to enter a nudist spring. At the hospital, Walter finally expresses his feelings for long-time fatherly friend Cabe, who reciprocates.
