In this finale, the tension hits a boiling point. Brenda invites George over, and the implication is heavy. Just as the show has been building toward the inevitable breakdown of George and Mary’s marriage (as established in The Big Bang Theory lore), this episode pushes the needle significantly forward. It leaves viewers wondering just how far things went, setting up a massive cliffhanger for Season 5.
