It would seem that sooner or later, WandaVision could find itself on a direct collision course with Doctor Strange and the characters therein. Though the Disney+ series has dabbled in magic now for six weeks, the latest episode dives headfirstinto the darker side of mysticism. Though many questions were raised in "Breaking the Fourth Wall," nothing is arguably bigger than the identity of the mysterious book residing in Agatha's basement. No matter the case, some think it's a tome that could tie right to Stephen Strange (Benedict Cumberbatch).
