Watch 'Once Upon A Time' Season 4 Episode 19 Online: Will Cruella Get Her Happy Ending In 'Sympathy for the De Vil'? [VIDEO]

Tonight is an all-new episode of "Once Upon a Time" on ABC and we want to know if Cruella De Vil (Victoria Smurfit) will get her happy ending just like Ursula (Merrin Dungey). From the episode preview we know the villainess is hiding a dark secret and she will do anything to keep that secret from coming out including kidnapping and possibly killing Henry (Jared Gilmore).

In the previous episode "Heart of Gold" we took a little detour from the main storyline and we learn that Zelena the Wicked Witch (Rebecca Mader) is still alive and has been hiding in disguise as Merrian (Christia Laing), Robin Hood's (Sean Maguire) wife. We also learn that Zelena has been in on Gold's (Robert Carlyle) plan to find the author all along. This weeks new episode will get us back on track, kind of, and we will learn more about the villainess Cruella De Vil.

The synopsis for episode 19 "Sympathy for the De Vil" reads: "A young Cruella is confined to an attic by her mom, who uses Dalmatians to frighten her. Meanwhile, in present-day Storybrooke, Regina (Lana Parrilla) gains the upper hand with Gold and prepares to save Robin, but her attention shifts when Cruella abducts Henry." We also know from the promo trailer that the author will somehow be involved with Cruella's backstory.

Guest stars in "Sympathy for the De Vil" include Patrick Fischler as Isaac the author, Kristin Bauer van Straten as Maleficent, Anna Galvin as Madeline and Milli Wilkinson as a young Cruella.
