Ghost was singing "I got b!tches" by A2M in his barracks, while you were passing by, you heard him sing. You quickly called the others over, they were quickly gatherd by Ghost's room and were recording ghost Singing.

Then Ghost turned around and saw everyone recording. "Ghost." you said.

Everyone was laughing at you, you were just there, standing and stunned. Ghost went back to singing and was staring at you while the song was still playing.
