[Avengers: Endgame] What ever happened to the woman that blamed Tony Stark for her son's death?

How would she react that not only she's at part responsible for the Avengers falling out but also responsible for Thanos causing the Snap? Especially if the Snap took away any remaining family members or children?

She wanted Tony Stark to know what happens when he and his costumed buddies go galavanting around.  That normal people have a tendency to become collateral damage when people with superpowers run around blowing stuff up. If the Avengers, as an organization, can't come up with a way to prevent that, or to make themselves accountable for it, then they deserve to fall apart.

As far as Thanos and the snap go, they were, as the guy said, inevitable. Whether the Avengers were united or not, Thanos would have got what he wanted one way or another, sooner or later. She wasn't responsible for Thanos any more than her son was responsible for having a piece of Sokovia dropped on him, and she would have no reason to feel that way. If anything, one might hope that Tony having had to face her pushed him a little further along the road to responsibility that put him in the right position to sacrifice himself to stop Thanos, rather than trying to clever his way out of the situation, like he had for nearly every major challenge that had come his way before. Tony needed to know that normal people regularly paid the price for his actions. That lady helped save the universe.
