In the Young Sheldon episode “A Sneeze, Detention, and Sissy Spacek,” the flu hits Medford. Nine-year-old germophobe Sheldon (Iain Armitage) goes to great pains to protect himself. He dons a mask, surgical gloves and creates a bubble environment in the garage. His excessive behavior eventually lands him in the principal’s office — and detention.
Cowboy boot wearing Principal Petersen is portrayed by Rex Linn. He’s known for his roles on Lethal Weapon (Riggs’ father Nathan), Better Call Saul (Kevin Wachtell), Nashville (Will Lexington’s father), and CSI: Miami with David Caruso (Frank Tripp), among many others. Young Sheldon airs Thursdays at 8:30pm on CBS, right after The Big Bang Theory, and right before Mom.
