Everyone was separated into a group with the time machine to collect the Infinity Stones. Steve and Tony also took on the task of collecting the Space Stone. Steve and Tony first returned to 2012, but since they could not get the stone there, they changed the plan and went to retrieve the Tesseract from Camp Lehigh, New Jersey in 1970.

Steve disguised himself by wearing his military uniform. Tony took the role of a doctor from the special team and went to get the Space Stone. Steve was also in charge of taking the red serum.

While Steve was walking down the corridor after taking the serum, he saw that the woman in the elevator was looking for Tony and himself with the soldiers next to her, and he immediately entered the room he did not know.

Steve exhaled as he looked around the room, suddenly catching sight of the photo of himself before his transformation into the super soldier on the table. Steve raised his eyebrows and took the frame in his hand. Steve turned around, frowning, and gasped when he saw the name written on the door. The woman, his old love from the 40's he could never forget, whose photo he always had in his pocket. The only woman he's ever loved in his life.

When the door suddenly opened in the other room leading to the room, Steve immediately approached the window and froze at the woman he saw.

You were giving some instructions to an agent. Steve watched you through the blinds with shaky eyes. 'The woman...' Steve said to himself. While you approached and looked at the files in front of the window, Steve was watching you behind the blinds on the other side of the window.
