CinemaBlend The following story gets into HEAVY spoilers for episode 6 of WandaVision, so do NOT read forward if you havenât yet caught up with the show, and its latest installment. The Hex is an anomaly in WandaVision. From what we know about it, it was created by Wanda (Elizabeth Olsen) to establish a safe zone of artificial reality where she and her soul mate, Vision (Paul Bettany), could live out the happily ever after that Thanos (Josh Brolin) took from them after he plucked the Mind Stone out of Visionâs forehead. The Hex is made up of âa colossal amount of CMBR,â according to Kat Denningsâ plucky Darcy Lewis. That stands for Cosmic Microwave Background Radiation, and it traces back to the Big Bang, as we learned in episode four. At the end of this latest episode, Wanda expanded her Hex for the purpose of getting Vision back inside of it.
