The 'Agatha All Along' meme originated from the 2021 Disney+ series WandaVision, specifically during the climax of the seventh episode where Agnes reveals her true identity as the powerful witch Agatha Harkness. Accompanied by a catchy, Munsters-style theme song, the sequence showed Agatha manipulating various events throughout the show’s sitcom-inspired reality. The meme usually features a screenshot of Kathryn Hahn winking at the camera or the stylized title card. It is widely used to humorously reveal a hidden culprit or a 'mastermind' behind minor inconveniences and major plot twists alike, capturing the playful but devious energy of the character’s reveal.
