The Show Ended How It Started

The show ended how it started. A soul of one of the two characters died and their way back in the real world and finding the other. The beginning Billy died and became William Kaplan and eventually he found Agatha. Agatha died at the end, but came back as a ghost and went to Billy. Then they both go a journey (down the "Witches' Road" and Find Tommy).
