a good response to the question “how old are you?” is something along the lines of “dunno i stopped counting after the first few centuries”
and it needs to be said seriously without smiling or humor or as casually as possible and followed by “so anyway” and a subject change as if it’s completely normal
"I stopped counting a few decades ago. no. what’s the one with the zeros? millennia that’s it. human time keeping is so confusing."
Peggy is the one to get stuck in ice in and survive the century. Pepper doesn’t get rid of Extremis and becomes Rescue. Bruce Banner stays under the radar leaving Betty as the authority in gamma radiation. Jane retains some of the Aether’s powers. Thor is busy ruling Asgard, therefore Sif is the one tasked to retrieve the Tesseract. Director Fury rounds them all up along with Black Widow for his Avengers Initiative and, Barton being compromised, Maria Hill steps up as the marksman of the team.
tldr; the ladies save the world instead
