In your last mission with Leon, you rescued Ashley, the president's daughter, from Spain. When you returned Ashley safely to her father, the president threw a ball to celebrate and you were invited.

You had gone to prom with your long-time partner Leon and the ambiance was just like proms in the movies. Men in suits and women in fancy dresses.

There was a karaoke competition organized as a small event at the prom and you wanted to participate in this competition, even if it was just for fun. When you got on stage, you started singing the song Zombie by The Cranberries with all your emotion and your best voice. This song reminded you of what happened that day of the mission. Leon was watching you as you sang the song.
