'Scorpion' Season 2: 'Super Fun Guys' Plot Revealed, Stolen Nukes & Movie Sets

Walter (Elyse Gabel) and Paige (Katharine McPhee) know they want to jump each other's bones, but the coworkers have resolved to keep their feelings to themselves. Although hiding under a pile of lies is always the best way to go in these situations, Paige will soon find there is one person she can't fool - Walter's mom.

Mr. O'Brien (Glenn Keogh) and Mrs. O'Brien (Pamela Shafer) will drop by the City of Angels in season 2, and Shafer's character will be quick to see through her son's charade.

"A family crisis of sorts brings the 'rents to town later this #fall, and it doesn't take mom long to figure out that #Paige is hot for her son," TV Line announced on Tuesday.
