For some reason you forced Lilth to come and visit Lucifer since he was depressed, once she came, she was there for a while, and you would hang with them while they were being Husband and Wife, so was Alastor too, so while your watching from a far, Alastor was joing in on you, not cause he was jealous or anything..whaaat??

You: This is getting goood...~, are you sure your not jealous?

Alastor: i can a sure of you dear~ theres nothing to be jealous of! his radio voice glitched a bit, his toothy grin getting wider
