Fans of ABC's Once Upon a Time were shocked when Emma Swan killed Cruella during the previous episode. While it was argued that Emma was only doing it to save Henry's life, there are already rumors that reveal that Emma will eventually give in to the darkness. 

Once Upon a Time Season 4 Spoilers have reported that Emma will be facing the consequences of her actions. Emma has grown a lot since the first season, and while she still struggles with her powers, her actions in killing Cruella have revealed a rather unusual side to her. '

"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," show creator Adam Horowitz said. "Emma has crossed a line." 

Emma will be finding herself lost and shocked over her heartless actions, wondering if her heart will turn as black as Mr. Gold's. While she has not turned full evil yet, she has the full potential to be. 

It also came as a major shocker that Emma's fate is intertwined with Maleficent's daughter, Lily. It was revealed that Lily had absorbed all of Emma's potential for darkness. The two were bonded by fate, and Lily would return to put her childhood friend back on the right track. 

Fans of the the Robin Hood and Regina pairing were also shocked when it was revealed that Zelena is back. Apparently, Maid Marian had been killed by Zelena back in the Enchanted Forest. Maid Marian's return to Robin Hood's life came as an annoyance to the Outlaw Queen fans, and this twist came as rather welcome news. However, the latest episode came as quite a shock when news revealed that Zelena is now pregnant with Robin's baby. 

This will take Zelena and Regina's rivalry to a whole new level as Robin Hood is Regina's true love. It will be interesting to see these two powerful witches square off in a duel once again. Only one sister will emerge victorious, who will it be?
