What Is WandaVision About? Theories
11 Ways WandaVision Could Lead the MCU Into a Wild Era of Mutants, Magic, and More

Jumping off the previous theory, the biggest clues to Mephisto's presence in WandaVision all have one person in common: Agnes. Big Red has a penchant for shapeshifting into animals, and who is always on hand-delivering animals to Wanda or Vision? Agnes herself! First, there was the lobster and then the rabbit, though the stork in episode three had nothing to do with her. (Although she was outside the house when it was there as well.) Speaking of the stubborn stork, when Wanda attempted to spell it away, the only thing that appeared was a thick red fog. Considering Wanda's magic couldn't work on it, it seems likely that it was Mephisto keeping an eye on his creations (the children) rather than Wanda's magic gone awry. A popular theory is that Mephisto is actually Agnes's absent husband Ralph. There's no explanation for why the witch would be working with the wicked villain, but it's safe to guess that it isn't necessarily willingly. Maybe Agnes struck a deal to keep her haven of witches safe?
