Rebecca Mader steps back into the green skin of Zelena on Once Upon a Time

Zelena (Rebecca Mader) is back on “Once Upon a Time” and she’s more wicked than ever before. 
The Wicked Witch has earned her title on the show already when she killed Neal (Michael-Raymond James) — but now she’s made herself the true villain by sabotaging Regina’s (Lana Parrilla) happy ending. 
In “Heart of Gold,” its revealed that Zelena didn’t die in the jail cell in Season 3 after Rumpelstiltskin (Robert Carlyle) stabbed her. Instead, she slipped through the time portal with Emma (Jennifer Morrison) and Hook (Colin O’Donoghue). 
While back in the Enchanted Forest, she killed Marian (Christie Laing) and took her body so she could slip back to Storybrooke when Emma and Hook made their way back. She’s been masquerading as Marian ever since, waiting for her chance to usurp Robin Hood’s (Sean Maguire) heart from Regina. 
What does that mean exactly? Fans have debated whether Robin was still honorable as he pined for Regina while being with Marian. That debate is now mute as they were unknowingly rooting for him to end up with Zelena. 
What’s worse is that Zelena’s plan finally seems to be paying off now that she’s blackmailed Rumpelstiltskin into working with her. In flashbacks of Rumple’s exile in New York he convinced Robin to stay with Marian and now he’s given up trying to find a way back to Regina. 
Now Regina must decide between helping Rumple turn Emma to the dark side so he won’t tell Zelena to kill Robin, or she can sacrifice her true love to stay true to the side of the heroes. 
Regina’s dark look at the end of the episode hints that she may take Rumple up on his deal, but no one should think that the Evil Queen will take being forced into a corner lightly. Zelena and Rumple have now threatened the thing that means most to Regina and her returning to the dark side cannot possibly end well for either of them. 
As heroes and villains alike continue on their quest for happy endings, Regina is not the person to make your enemy. While Zelena has proven she’s definitely the more evil of the two sisters, Regina is the most powerful and she will do whatever it takes to protect Robin from harm. 
This major twist in the season is setting up one epic battle for the season finale. Will Regina have to take out both Rumple and her sister? 
“Once Upon a Time” continues Sunday at 8 p.m. ET/PT on ABC.
