58: "Old Souls" (S4:E12)

Our hearts are full, and we might still be a bit sniffly after watching the season 4 finale. Sure. There may have been some throat slicing and haunted wedding dresses, but mostly this was a deeply satisfying conclusion. And so we end this season with deeply contented sighs.
