Bucky/Peggy
Peggy had left Stevie to an adult who could actually keep up with him better than she could so her ravishing hunger could be well sated. Peggy hadn't forgotten the elder of the Buckys and had indeed brought along something for him too.
As soon as she spotted him alone, Peg came up behind him, tapping his shoulder. "I do believe a happy birthday to you is in order for the day, Sergeant Barnes." in her hand, she held a beautifully wrapped present.
