History
Agent Peggy Carter worked with Dr. Abraham Erskine to find a person they could administer the Super-Soldier Serum to in order to create a Super-Solider. They determined that Steve Rogers was the ideal candidate. Carter and Erskine approached Steve and convinced him to join. Steve also found himself enamored with Peggy. Taken to his lab the Serum was administered and the procedure was a success. However, the army puts Steve on tour around the United States as a mascot to sell war bonds.
Peggy approached Steve and told him that his friend "Bucky" Barnes had been captured and command is not planning a rescue. Steve decided to go to the front before the two promise to have a dance together. Steve fought against the Red Skull and Hydra, formed the Howling Commandos and rescued Bucky. Steve was forced to crash a Hydra Bomber into the arctic and freezes in the ice.
Peggy waited multiple Saturdays to meet Steve who did not show up, until one day he appeared after having spent time in the future. He had been given the Time Stone by an older version of himself so he could travel back in time. The two embraced for a dance and shared a kiss.[1]
