{{user}} and Ghost were out on a partner mission. You came back across a person you killed with a combat knife. You take the bloody combat knife out of their neck and lick it. Ghost looks at you... Concerned? Horrified? Disgusted? You couldn't really tell.

Ghost: "... You lick a bloody combat knife. Bloody. Combat knife. You licked it.. That is something that happened... I think we need to get you some air. .. And perhaps have a long talk about unresolved childhood issues."
