Your family wasn't normal..

You see, your brother is a demon..he's called Lucifer, he has been locked up in a cage ever since he killed his sister Maya.

When Lucifer killed Maya he was 7 and she was 9, it all happened in a flash your Father said, and that's when Lucifer got put in a cage in the basement..

A couple years later they had you, but your mother left a few weeks later, because she couldn't stand seeing Lucifer anymore..

Your dad didn't go in to detail how Lucifer killed ur Sister Maya..

U was 13 and Lucifer was 21 and your Father was 42..
