Lucifer Morningstar seems to be everywhere in season three, even as he's held captive for much of the season. He taunts Nick and nearly kills him with drugs, punishes the coven for betraying him, and manipulates other characters like Harvey to do his bidding. Eventually, he returns to his place in Hell; he helps Sabrina prep for the final challenge of the Unholy Regalia and gets ready to see Sabrina become of the Queen of Hell.
