ABC fairytale drama series Once Upon A Time returns with another interesting episode of season 6 this Sunday, November 6, at 8 pm EST. Episode 7 is titled Heartless and it will focus on The Evil Queen's ultimate revenge against Snow White a.k.a Mary Margaret Blanchard.

The official synopsis for the sequel states that the dark side of Regina Mills will threaten to destroy the town and everyone in it unless Prince Charming a.k.a. David Nolan and his wife surrender their hearts to her.

The Evil Queen seems quite confident about her mission as the promo shows her telling the Wicked Witch of the West Zelena that she is finally getting her revenge on Snow White. "Soon I will have their little-shared heart beating in the palm of my hand," she says.

So Emma Swan will seek the help of Captain Hook a.k.a Killian Jones and Henry Mills to defend Storybrooke and Regina will help Snow and Charming to search for a magical sapling created by the first spark of true love. Lana Parrilla's character will even try to use Gold's and the Evil Queen's burgeoning romance against them.
