Someone tried to make a deal with Leo, but he chooses Eva. The WWW could be related to Cora as it is true she certainly has the red hair and curls, plus we’ve seen how she’s dressing up as Regina more or less, as if trying to take her spot. Maybe they were switched at birth but Regina seems to resemble Henry Sr./Xavier so I do think she is Cora and Henry’s child. I like the twin babies idea, where Cora ends up making a deal with Rumple about WWW to save Regina as a perfect baby.
I mean those guys are brothers, not even twins. (Charlie Sheen and Emilio Estevez) . First famous full siblings I could think of but sure there are better examples of people with even more startling a difference. (With these two it is personality that’s the bigger difference). Maybe it could tie into the apple tree (long forgotten apple tree). Perhaps thats the “root” of how the sisters fates are tied together that one bears the brunt of all the magical side effects of the magic the other one does.
I agree KFC…appareantly the “Red” and “Green” apples didn’t fall far from Cora’s tree… 😛
