goddamnit, I wish I could drink. Okay. Different universe, timeline, whatever. The way it went for me, Steve got the serum, pulled me and the others from Azzano, I fell off the train in the Alps and everyone thought I was dead, but I got picked up by Hydra. Zola gave me something close enough to the serum in Azzano that I survived the fall. They did a lot of didn't die with the Red Skull. Steve thought he took out the Red Skull when he crashed a fucking nuclear-armed plane in the Arctic to save the world, and he was frozen in the ice until someone thawed him out in 2012. Hydra had been keeping me on ice as their private assassin/weapon while they grew inside SHIELD (which was a world security taskforce that YOU started after the war) in secret. Steve resurfaced in time to fight an alien invasion in NYC, and a few years later he stopped HYDRA from taking over the world and managed to break me out of their brainwashing, too. Lots more fighting happened, I'm 106 years old, and I need a lot more time and alcohol to give you all the gory details.
And that's not even getting started on this place.
