Lovessmurfs… I just posted the same theory on Hat Trick See below:
After watching last night’s episode “The Stable Boy,” I am more convinced than ever that Regina has an older sibling. We now know (for sure) that Cora is the Miller’s daughter. She makes quite a few references about sacrifices for power in Stable Boy. I DO NOT feel she was able to keep her first born from Rumple (One of the many sacrifices she needed to make). I also feel she too had to sacrifice her true love, hence her diatribe about love being an illusion. Is the QOH Regina’s sister, can’t say for sure. But she is the Queen of HEARTS and we have now seen that pulling out and keeping hearts is a family trait.
