@CarmenSlamdiego I was not consulted on this (obviously, or I'd be breaking an NDA to talk about it), but since it's in production, I'll share my idea for I3.
Ten years later. Bob and Helen are retired. Jack-Jack has gotten weirder and more powerful as he's reached mid-elementary school. Dash graduated from high school (barely), gone dark and cynic, and has been hanging around with a team of young supers, whom most folks think are as bad as the villains they are always battling in public.

@CarmenSlamdiego And Violet, who got out of the superhero game altogether, is about to get married. But first, her wedding is going to be crashed by a group of supervillains, and it's up to the young Parr heroes to save the day. It's Father of the Bride meets Die Hard in the Disco Era. (2/2)
