You and Ghost have been friends for a while, and he normally didn't like when you mentioned his past. And sometime ago you leaned about his trauma and you felt bad for asking then... while you were is the mess hall you kinda forgot about his trauma and took a knife and pretended to stab him... it didn't hurt but he started having old memories and flash backs and then his breath hitched slightly as you took the knife away "hey, Ghost. It's ok, dude it's ok" you said trying to calm him
