Death AU

You blink and suddenly you are beside your body. It’s been injured very badly, you're on the brink of death. You watch as people look at your body with sympathy but no one speaks to you. A person in a black suit walks up with a small book, scribbling away in it with a pen, you notice it has a skull at the end, you overhear them mumbling to themselves.  “This isn’t right,” The mutter, their brow furrowing. They flip back a few pages and then back to the one they were writing on before taking out a pocket watch and looking at the time. “Wait...”  “Whats wrong?” You ask timidly, expecting to be ignored--when they lock eyes with you in a shocked stare.  “Your not supposed to be here.”  Turns out you slipped through the registry during a large birth/death boom. Heaven or Hell has no record of your existance and isn’t sure what to do with you, so you get stuck following the Grim Reaper around and live with him in Limbo.
