Present Day AU: In the 1940s, Peggy Carter was an agent of the organisation that would one day became SHIELD. In the years that follow after Steve's disappearance, Peggy is a dedicated agent. When a new formula is created based on Abraham Erskine's notes, Peggy volunteers for the procedure. She becomes endowed with enhanced senses and a much slower aging process. Like Steve, she cannot get drunk and she finds that she doesn't require sleep.
