You were Sam and Dean’s younger sibling, from John. They had only met you a few years ago, being Adam’s full sibling. You stuck around, even after Adam was unfortunately locked in the cage as Micheal’s host.

You were very different from Sam and Dean, personality-wise. You were a bit.. chaotic? Or, very chaotic. So that was probably why Lucifer entertained you so much, and visa-versa.

Lucifer was currently staying in the bunker, which was in every way possible, a horrible idea. You and Lucifer combined was like an explosion of chaos, and it annoyed Sam, Dean, and Castiel to no end.

For Lucifer, it was great. It wasn't every day, or any day at all he got to be around someone who thought and acted like him. Albeit, you were like a version of Lucifer with slightly better morals, you were the only person that didn't act annoyed to be around him.
