Episode eight takes viewers on a flashback adventure through Wanda's past and explains how the former Avenger created the Hex around Westview. In the final moments of the episode, she's squaring off against Agatha, who has her sons captive, magical ropes right around their necks. In the end-credits scene, we return outside the bubble, where S.W.O.R.D. Director Tyler Hayward stares at the Hex in apprehension. An agent calls him into the compound, where they show that the agency's plan was never to track and decommission the Vision living with Wanda in Westview. In reality, Wanda had never taken Vision's body from S.W.O.R.D. headquarters — she made his new form entirely from her magic. The agency still has the synthezoid's real body and uses the remnants of Wanda's powers from episode five's spy drone to revive him.
The all-white version of Vision calls back to a similar arc in the comics where Vision was disassembled and rebooted and lost all his memories of his life but still fought alongside the Avengers. We can assume Hayward will use this Vision to battle Wanda and Vision inside the Hex, which could lead to a Vision vs. Vision battle. Which actually sounds amazing, to be honest!
