- Only Cap and BW saw the information from Arnim Zola in the bunker.
- My interpretation was she couldn't hold the explosion so she forced it up into the air and it exploded when she couldn't hold it anymore. Still, it was clear she was trying to help. I also agree with your take that "how would the UN have handled things differently". Although, the entire Ultron situation was, in fact, Tony Stark's (and Banner somewhat) fault. Technically, he is partly responsible for any death's Ultron caused.
