As Young Sheldon prepares to wrap up its 7-season run, a few plotlines and loose ends from The Big Bang Theory need tying up. One of these is what the entire show has been building toward: George Sr.'s death. While the show has seemingly confirmed that this will be addressed, he's still alive and well as of this writing. The other life-changing event involves Sheldon walking in on his father with another woman. The shock of seeing this led the boy genius to adopt his familiar three-knock greeting. In the most recent episode, "Ants on a Log and a Cheating Winker," the show finally takes on this plot point. Well, sort of.
