Plot summary
When Happy's new online friend Ada, a teenage girl she met on a website for female mechanics, doesn't respond to a private chat, Happy heads to Ada's hometown of Lancaster. She enlists Scorpion to help her move Ada, who has a severe immunodeficiency brought on by aplastic anemia, and the sterile bubble that protects her weak immune system to a germ-free location after a severe storm leaves her home surrounded by dangerous debris. Meanwhile, Walter tries out his newfound emotional state on Paige when she and Tim break up after he decides to accept an eight-month contract extension in Jordan.
Later, Sly loses the alderman election after Allie's boss and Sly's opponent forces her to post a photo on the internet of the germophobic Sly shaking hands with a veteran and wiping his hand afterwards. This causes Cabe to break up with Allie, although Sly nonetheless manages to save the Warlock's Chest from being condemned by qualifying it as a historical landmark. Also, the team holds a Winter Formal and uses a virtual reality headset designed by Walter to allow Ada to experience the dance.
