God, he's tired. Going back to hell will almost be a relief. ]

It isn't that simple, [ He says, breaking back a little, giving her a small smile. ]

"The first seal shall be broken when a righteous man sheds blood in Hell." It was me. I started everything, and now my brother betrayed me, didn't listen to me, didn't trust me, consorted with a demon and chose and trusted her over me, and broke Lucifer free.
