Plot summary
Scorpion is back to normal with the regular roster after Tim's departure, but Paige is upset about how Walter handled the situation and just wants to focus on work. Meanwhile, Cabe is moving out of Happy's home and she is actually sad about it; he gives her his mother's brooch to wear on her wedding day and she considers him a friend. 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.
The team must collect various materials, forcing Sly and Happy to face their fears and Paige and Walter to enter a nudist spring. Later, at the hospital, Walter finally expresses his feelings for his long-time fatherly friend and tells Cabe he loves him.
