"Plutonium Is Forever"
To fix a Los Angeles nuclear reactor that's on the verge of a cataclysmic meltdown, Walter and the team must reluctantly enlist the help of a troubled former member.
There are some things that happen on Scorpion that only geniuses would do.
Against Cabe's advice, Team Scorpion heads to Las Vegas for a simple casino job, but a robbery leads to Walter's arrest and the rest of the team is left to clear his name.
If everyone were like Paige we wouldn't need a team of geniuses to solve our problems, because we wouldn't have any problems.
