This episode gave us sort of a Christmas Carol-like story without copying the structure or phoning it in. It focuses on Julian, who gets a kind of Scrooge-like development, but it's the ghost that's changed by the living, in this case a human baby he's unceremoniously left with, who seems to like him for some reason. How the baby can see him or know he's there is questionable. Maybe it's a witch like Mary accused Alison of being. Julian is still the same awful person he's always been, but we get to see an alarming vulnerable side to him.
