The 21st episode of Season 10 of Supernatural, “Dark Dynasty,” lives up to its name. Heed our warning—“Dark Dynasty” is full of gore, lies, and heartbreak. On the fun side, we get a cool literary reference and new monster lore. Not that it makes up for the extremely distressing ending. We don’t normally warn about spoilers because if something is called a “recap” the spoiler aspect is pretty much implied, but here we will warn you: watch the episode, have yourself a good cry, then come back and read this recap.
