This approach actually fits with comments from Kevin Feige about retconning Scarlet Witch back in 2016. While promoting Doctor Strange, Feige made a throwaway comment about Wanda’s powers as well. “Her powers, she’s never had any training,” he observed, “I’m talking about Scarlet Witch. She never had any training; she’s figuring it out. Arguably, you could say that that’s why her powers are much more chaotic and much more loose in the way that we showcased those light effects. In [Doctor Strange], some of what you might see today, even the cover of Entertainment Weekly, it’s much tighter. It’s all about focus. It’s all about pulling energies from other dimensions in an organized and purposeful fashion, which is why they can do a lot more than she can in, at least, a much more precise way.” It looks as though Marvel’s plans for Scarlet Witch have not changed.
Of course, it is possible Marvel will choose what could be called a “double retcon,” revealing Wanda as both a mutant and a sorceress. This is, however, unlikely; while the comics themselves are full of retcons, this is a result of differing creative teams over the decades. It is difficult to believe Marvel Studios – which benefits from the singular vision of Kevin Feige – will ever choose to indulge in retcons to the same degree as the comics. To paraphrase Oscar Wilde, one retcon is unfortunate; two looks like carelessness. And so, it seems the die is cast; the MCU is officially retconning Scarlet Witch as a sorceress in WandaVision, not as a mutant.
