Non-highlighting because it's from an older episode. My roommate has a pretty good theory on who Cora is. Mostly because of in the Regina flashback earlier this season with Rumpel giving her the magic book and his comment about knowing her when she was a baby. She thinks Cora is the miller's daughter in the original Rumpelstiltskin story. Now granted, Henry Sr wasn't a king, but it's definitely plausible. As for last episode: Spoiler We had a debate earlier about if Lancelot was really just Cora, how did Cora recognize Snow AND know her and Lancelot's backstory? Or was that actually Lancelot that greeted her. Snow recognized Cora, yes, because she looks the same, but the last time (that we know) that Cora saw Snow, Snow was just a young girl.
