“There was. There was a son. I lost him — as I did his mother.”
Rumple says this to Belle in “Skin Deep.”. Does this jibe with Cora being Bae’s mother? I just don’t see how that can be, not because of the time passage (because Cora is a witch and may not age as others do) but because Rumple had Bae before he got power and started making deals.
