"Once Upon a Time" season 7 just revealed its biggest twist, so far, and fans were surprised. Viewers believe that Drizella (Adelaide Kane) seems to be the one who cast the curse, and now, for once, Roni (Lana Parrilla) does not know what to do.

In last week's episode titled "Wake Up Call," Roni saw a photo of herself with the young Henry (Jared S. Gilmore). When she was brought to the past and Drizella woke her up from the curse, she remembered everything and learned that she used to be Regina.

Regina tried to strangle Drizella, but she forgot that she had no power. "There's no magic in this world, I don't have magic," she said. As Kane's character was trying to convince her, she told Parrilla's character why the curse happened in the first place and the consequences of breaking it in "Once Upon a Time" season 7.

Now, Regina will be the one who will decide about Henry (Andrew J. West) and Jacinda's (Dania Ramirez) relationship. But with Drizella around, there might be a chance that Regina will just let the couple stay apart to save everyone.

In an interview with Entertainment Weekly, Parrilla talked about Roni's future and the unexpected twist they just revealed. "She's in a complete state of shock," the actress said about her character's experience. When Drizella woke Roni up, she was still trying to understand everything.

Parrilla explained that Regina is afraid of breaking the curse and the negative effects of it. She is now responsible for what the right thing to do is with the curse. As she is thinking of a way to break without hurting other people, she knows bad things are going to happen to the ones she loves.

"Once Upon a Time" season 7 airs every Friday at 8 p.m. EST on ABC.
