Battle
Peggy Carter returned to her apartment from La Martinique with the Nitramene to find her roommate Colleen O'Brien sick in bed. Carter entered the bathroom to prepare a solution of sodium hydrogen carbonate and acetate using a combination of baking soda and vinegar. Carter used the solution to successfully neutralize the Nitramene and poured a drink. Carter heard a noise coming from the bedroom and went to investigate. Carter approached the bed and pulled back the cover to find Colleen had been shot in the head. The Man in a Green Suit exited the closet behind Carter and took aim but Carter spotted him in the mirror and kicked him in the leg and grabbed his gun. The two struggled briefly over the weapon until Carter was able to knock it out of his hand. Green Suit threw Carter against the wall and Carter saw a peculiar scar in the man's throat. Carter put the man's hand on the burning stove and he picked up a knife from the sink. Carter dodged several knife attacks before throwing the man out the window. Carter ran to the window but the man was gone.
