The team -- dubbed Scorpion -- includes behaviorist Toby Curtis, mechanical prodigy Happy Quinn, and statistics guru Sylvester Dodd. While comfortable with one another, the team members struggle with understanding life outside their circle, so when they need help translating societal cues, they rely on the skills of Paige Dineen, a woman with a gifted young son.
