===[[13.05 Advanced Thanatology]]===
After briefly committing suicide in an effort to learn from the ghosts trapped in the Meadows House where their bodies are hidden, Dean is greeted by [[Billie]] who is the new Death. Billie reveals that one of the laws of reality is that when one incarnation of Death dies, the next [[
Reaper]] to die will take his place.
After being resurrected by Billie, Dean tells Sam about his encounter with Death. Sam is confused as Dean killed Death leading Dean to explain that Billie is now the replacement of the Death that Dean had killed.
