Jack frowned. He hated having to be mean, but John wasn't exactly making it easy for him to be nice, either. "It's not a contradiction if it's pity. And yes, John, I pity you, all right? I think you're sad and you're lonely, but you're too damn prideful to change anything, so you lash out and find unhealthy ways to cope, because it's easier that way. It's less wanting to be with you and more looking after you."
