Before the episode ends with this timeless laugh, viewers are treated to the rare moment of vulnerability from the Spock-like scientist. Sheldon confides in Leonard about his insecurities and anxieties with change, falling behind his friends, and taking the next step with Amy (Mayim Bialik). These factors lead Sheldon to run away from his problems before finally mustering up the courage to confront them face to face.
He gives an inspiring speech to Amy and Leonard that suggests he may have actually changed during his unique and treacherous journey. Sheldon enters his apartment as a seemingly new man until he sees Penny's new hairdo, which even shocked "The Big Bang Theory" creator Chuck Lorre. He immediately freaks out at the sudden change and walks right back out of the apartment to avoid the difference.
This shows Sheldon is ultimately stuck in his ways, though he is able to make some progress with the loving Amy by his side. His quirk delivers one of the funniest scenes in Season 8 by also playing off a real-life choice that makes the scene even more hilarious. It also kicks off Season 8 on a high note as it continues to give viewers more silly scenes with our favorite characters.
