I think people need to temper their expectations for the Client’s identity in VisionQuest. Terry Matalas has made it clear that this isn’t a Mephisto-style reveal or a setup for some massive MCU cameo. He’s ruled out theories involving Wiccan, Doctor Doom and Iron Man, and emphasised that the identity matters because of what it means for Vision’s personal journey. I just hope people take his comments on board rather than expecting a huge twist and being disappointed when the reveal comes.
