So I wonder about Vision's fate.
It has been hinted for a while Vision is not the original Vision. He do not have memories, he can't survive outside of Wanda's Hex, Wanda stated she cannot bring back the dead, and in that episode Vision sayed for him it seems like Vision's past happens to another person.
So at best he is Vision 2, a recreated one rather than the original or at worst he is just a mental projection, anyway it does not look like there is much hope for him.
However it seems that Agatha is after the twins. Meaning they are "real enough" to be of any use outside the hex. Shouldn't the same be true for Vision ?
Anyway, I don't think it's going to be for an ending where Vision is surviving, it would mess up the message about grief and accepting that was is done cannot be fixed. I hardly think the message will be "well, actually you can".
