WandaVision: 5 Predictions For Who The Final Episode's Secret Cameo Is
5. Doctor Strange
On the same day that Kevin Feige first announced WandaVision all those months ago, he also confirmed that the series would directly tie in to Doctor Strange in the Multiverse of Madness. Since Elizabeth Olsen will be joining Benedict Cumberbatch in the movie, Doctor Strange is one of the most obvious options to bring to Westview in WandaVision's finale.
Though Paul Bettany seemed to suggest that the Sorcerer Supreme wasn't the cameo he was speaking about, fans shouldn't take exactly what he says as gospel. This could have been little more than a deception to throw everyone off the scent.
As Wong told Stephen Strange not long after he first came to Kamar-Taj, while the Avengers protect the world from physical dangers, sorcerers like them look to more mystical, magical threats. It doesn't get much more mystical than the Scarlet Witch's Hex, and especially so, when you consider the possibility she may also be a Nexus Being.
When Wanda first created her new sitcom life, Agatha Harkness was able to sense the power of the spells being cast, and it's impossible to think the same thing didn't happen with Doctor Strange. Westview is surely on his radar, and with there being no clear links between WandaVision and the Multiverse of Madness revealed so far, the Sorcerer Supreme may make the short journey from New York to New Jersey for the finale.
