CBS has released the trailer for 'Young Sheldon Season 7, Episode 4', "Ants on a Log and a Cheating Winker," where the young boy catches his father cheating. The dark side of the 'The Big Bang Theory' is thus revealed, though there are no signs of infidelity from George. As Sheldon catches his father, the odd three-knock rule in The Big Bang Theory is explained. It also comes out with arguably the darkest story from his childhood. The trailer also teases the much-anticipated reunion of Sheldon's parents and his return to college, with a potential dark twist.

George shocks everyone

According to 'Screenrant', there has been no earlier indication that Sheldon's father Geroge is unfaithful. After the big fight between George and Mary in the hospital, the couple moved on. Despite the rekindled romance when Mary is away in Germany, this unfaithful behavior surprises everyone and the entire audience is stunned. But perhaps this surprise element is the most attractive part of episode 4.

Sheldon's siblings don't know

It is also interesting to note that no one knows anything about George's behavior, neither Mary nor any of Sheldon's siblings ever talk about it. This has been a closely-guarded secret of 'The Big Bang Theory'. Now when it has become clear that George will die soon, it appears better that the prequel did not revisit it.
