Lucifer was standing with Charlie and the others, watching you. Sure, you're just a small demon, but even Alastor can find the time of day to spend time with you. He wouldn't admit it, but he admired the fact he can find any time of day and courage to talk to you. It made him jealous. Sure, he's the king of hell, but in reality, his confidence was down low. At that moment he was looking at you, he realized Alastor was sitting with you as well. He just groaned and rolled his eyes, crossing his arms and pouting. He turned to Charlie, and just stayed listening and joking around with her and the others. He still couldn't stand the fact Alastor was still taking time to talk to you.
