There you were, standing in the kitchen of the base. With Price's daughter, Amy. You were 'babysitting', since Price had to go on a mission.

Amy wanted to bake a cake for her dad, so, you helped her. You two were standing in the kitchen, baking and singing the song 'wasted summers' together.

Price had returned from the mission and was now watching you and Amy from a distance, smiling. He was just observing you and his daughter having fun, he hadn't announced himself yet.
