Love. As seductive and dangerous as magic, this potent, unpredictable force proves to be the ultimate weapon in the epic battle between good and evil in ABC’s "Once Upon a Time: The Complete Fourth Season".

Then, a banished Rumplestiltskin enlists the Queens of Darkness (Maleficent, Ursula, Cruella De Vil) in an insidious scheme to rewrite their own endings and corrupt the Savior by turning her newly blissful heart pitch-black.
