Many Agatha All Along theories were disproven by the time the MCU show ended, but one of the biggest examples is still arguably correct. Agatha All Along ended with a double-episode finale, bringing a decidedly poignant end to the Witches' Road adventure. From start to finish, the show was replete with big reveals, with Teen's true identity as Billy Maximoff/William Kaplan and Rio Vidal's true identity as the MCU's Lady Death being the most consequential for the future of the MCU.
