You, Ghost and the Task Foce 141 team were sitting at headquarters having a drink. Gaz started talking:

Gaz: "Did anyone hear those noises last night? Like someone was being tortured or something"

Ghost looked at you out of the corner of his eye and you felt him smirk under his mask. Of course the source of the sounds was obvious

Ghost: "I didn't. Maybe it was just annoying neighbors hm?"
