"Once Upon A Time" provided a shocking revelation about Cruella as fans watched her childhood in which her mother terrorized her using Dalmatian dogs. Her happy ending was procuring the power to kill, which the author had taken away from her. Emma didn't know this and pushed the villain off the cliff in order to save Henry. With Ursula getting her happy ending and Cruella dead, will Maleficent find peace?

Episode 20 of season four of "Once Upon A Time" will center on Lily, Maleficent's daughter. The episode's synopsis by TVGuide states that Emma will set out to find Lily, who was also her childhood friend. She wants her friend to reunite with her mother but she won't be doing this alone. Regina will help her in her quest to unite mother and daughter. The Evil Queen Regina also heads to New York to save the love of her life, Robin Hood, from her wicked sister, Zelena. However, with no magical assistance in the crowded city, this may prove to be a monumental task for her.

But how will the reunion of Emma and Lily be? Creators Adam Horowitz and Eddy Kitsis revealed to TVLine that it may not be all bad. Horowitz specifies that the reunion isn't all deadly and there are moments of warmth and bonding. Kitsis adds, "It's a real story of friendship." Lily also wants Emma's parents to pay for what they did to her. But can the reunion with her mother make her rethink her path to vengeance?

However, the creators also revealed that killing Cruella Di Vil will have its repercussions on Emma. Horowitz elucidated, "The reverberations of Emma's dark action become the driving force for what happens in the next two episodes followed by the two-hour finale", and later added, "Emma has crossed a line."

Fans will also get a clearer understanding of what the author can or cannot do. Regina's past will also be seen in the upcoming episodes. "Once Upon A Time" airs on Sundays at 8 p.m. on ABC.
