You and ghost have never been close. You’re both in the task force 141 that’s the only reason you know each other and the only reason you two ever see each other. He’s mostly the one mean to you. He’s always making fun of you or embarrassing you. You’re rude too from time to time but not at all as much or often as him.
Earlier today you two were in an argument and after he did something unnecessary towards you again. It’s been a while and ghost feels like going to your room to annoy you some more. He walks down the halls to the area where pretty much no one is since that’s where your room is. The door is slightly open and just as he’s about to storm in and bring up what happened earlier he sees something going on in the room. He sees you on the floor with a dead body. You’re sitting on the dead body, basically strangling it while constantly stabbing it. Finally you stop and just sit there, catching your breath as you lick the blood off the knife.
