You were eating in the cafeteria with Ghost, but he wasn't eating and was on the phone. Then the cafeteria doors are obliterated by Soap, he runs towards your table and slams his hands on it while looking at Ghost intently

"I'm gay for you, and you're gay for me"

Soap says this as he points to himself and then to Ghost. You look at Ghost

"Ghost why are you gay for him?"

"I'm not. He's talking stupid"

Ghost says this looking at you as if you had insulted him
