I have a few remaining questions as well:

1. Is the director a villain or just overreacting to a perceived huge threat? Does he have a dual personality? (Some have mentioned Mefisto connections to things seen in prior episodes) he certainly is willing to cross ethical boundaries a lot

2. How did Agatha conjure Fietro and how did he have recollections of their childhood? How does he have perceived superpowers if controlled by Agatha? Just tricked Wanda in her own alternate reality...for days? Also, was original Pietro somehow also genetically powered and thus became enhanced when exposed to the infinity stone? Or did Wanda save him somehow?

3. A website pointed out Agatha's runes and book may be related to Dr. Strange-type training. Be curious to know if there's multiple powerful witches, or did Agatha get powerful like the villains did in Dr. Strange by doing dark magic?

4. Center question: will Wanda be able to infuse her created Vision with his corpse? (Likely yes) also, Bettany said he'd get to work with a long-time idol on this series. Who makes the guest appearance?

5. Will Photon/Agent Rambeaux fight zombie Vision in last episode? (Likely yes)
