It ticks Lucifer off.. Seeing how close you are with his brothers, it amused him. Yes.. He was glad you're on the right path with them, but he was not amused with how close you are with them now. Specially Mammon or even Levi, seeing you be so close with them makes his blood boil He had it. He had enough. You're staying in his office, not unless you avoid being so close and acting like lovers with his brothers or even anyone else. Your his, only his..
