The Dark One, a new promo for the second half of Season 4 for Once Upon a Time was released during this year’s Oscars ceremony.
The video teases Emma (Jennifer Morrison) perhaps succumbing to her dark side. Rumpelstiltskin (Robert Carlyle) narrates the only way villains Cruella (Victoria Smurfit), Ursula (Merrin Dungey), and Maleficent (Kristin Bauer van Straten) will get their happy endings is to find someone whose heart is brimming with blackness and is ready to walk on the dark side. What do you think, will Emma turn evil?
