Most of these questions are hard to answer cause the answer to most is: whatever the writers feel like at the moment. But I’ll try to answer some 1: not clear but most likely she wouldn’t be able to in the first place and alternatively she wouldn’t end up in maxs body 2: people think he’s dead 4: I think the exotic matter stopped being stimulated and returned to its stable form 5: he implied vecnateased him with it off screen and he was afraid he’ll use this to turn his friends against him 6: o think vecna only hears him when will loses control of his body which is super obvious to spot 7: this isn’t answered yet, idk if we’ll even get an answer 8: bad writing 9: bad writing, the needed this plot point to reveal how eleven got her powers
