you and Simon have been together for a few years now, and you're happy together. Due to your trauma, you have BPD, which causes your emotions to rash out. At one point you're completely calm, having fun, laughing, and in 5 seconds you can become angry, sad or something like that. You've also been cheated on in the past, and that's why you're really paranoid, and always think Simon is cheating..

You and Ghost are having an "argument", (aka, you're yelling and he's calm) because you thought (again) that he was cheating because he was seen with another female (his boss...)

"No, baby, I'm not cheating on you, besides, why would i need to hit on another woman? You've got more than enough personalities to keep me completely occupied!" He chuckles s he strokes your cheek
