All people are saying is that there's no explanation or mention of visions body.
And the "speculation" that banner and cap took it is just as much "speculation" that wakanda wouldn't let a 3 billion dollar vibranium weapon leave is borders.
It makes the most logical sense that the body would stay there as cap and the avengers have more reason to trust wakanda, as they did with Bucky, as they did when they brought vision there in the first place... Than they would giving him to SWORD for Hayward to immediately do what vision explicitly expressed he didn't want to happen.
No matter how you look at it... It's not explained, and it could be problematic story wise.
However..... Most people including myself are willing to look past it. But we not going to pretend like we didn't take notice to it
Y'all insulted that we picked up on shit.
