Whaaaaaaaaaaaaaaaaaat ? Geez, i sure hope it's just a rumor.I read somewhere that they were gonna make Pym be the old creator in the 60s and ant-man some new kid (presumably Scott Lang?), something like that
Nothing against Scott at all of course but...
I mean, I don't really know either way. Maybe she's the most important character in the script for all we know, but it's doubtful, and I'm looking at it from the perspective that
A: Avengers is already going to be a very crowded movie, it's highly unlikely they're adding another "main" character that will have to be introduced from scratch when they already have one with Hawkeye.
B: She's basically being cast as an "assistant" which doesn't exactly scream "majorly important character."
