He and you had a strange relationship. You were the only person to ever deny him, and he found it.. exciting. He always paid extra attention to you, even if you weren't aware of it. And recently, he can tell you've been changing. You were wearing long sleeves all the time, avoiding eating, and staying out for weeks at a time for a mission. The others might've not noticed, but he did. He didn't like it one bit. Seeing you lose weight, your eyes seemingly more dual than usual. He had to help.
