Re: Avengers cartoon - Part 5
Yes, it's easily a gaff if the animators were told to just throw superheroes in the background of the memorial service, without bothering to check the status of the heroes on the show. They may have just used the animation model for Vision without thinking.
Now, I'm not saying it's definitely a mistake, but like I said, it's happened before. But, it could just as easily be a plot point.
