Avengers: Infinity War - 10 Things Marvel Don't Want You To Know
2. Shuri Tries To Remove Vision's Infinity Stone
The Spoiler:
Though Vision will be captured at some point by the Black Order, his redemption may come thanks to Wakanda's own version of Tony Stark - T'Challa's sister Shuri.
She might well remove the Infinity Stone from his forehead - presumably without killing him in the process. You'd hope.
The Evidence:
This is another one from LEGO, whose tie-in set Corvus Glaive Attacks features Glaive, Vision, Black Panther and Shuri and whose description intriguingly mentions Shuri removing "the Infinity Stone that controls the mind from the head of the Vision."
There's a chance that this might be how Vision ends up captured, but it seems odd that Edinburgh would have been used to double for Wakanda (since we know Vision is captured in the scenes shot in Scotland), so this could be later in the movie and it could see Vision freed from the Stone, which would be a smart inversion of the assumption that he's definitely going to be killed for it.
