Good point Obisgirl!
I’m wondering about Cinder’s speculation here–I guess it is possible that Rumple baby swapped Regina and Wicked. I’m not 100% on board with the idea because they cast Henry and Xavier in a way to align with Lana’s heritage, but who knows. Mader’s very pale (when not green!) with red hair and I suppose Cora had dark red /brown hair and was pale. I’d buy Cora had a 2nd kid, but doubt it was with Rumple, don’t see him going near her again romantically. I could see him getting a deal out of Cora for a 2nd kid though, after whatever events led to Xavier’s kingdom no longer existing/Cora & Henry Sr. no longer being royalty just nobility, which then resulted in some kind of “truce” of sorts that lasted a long time until Regina’s marriage when Rumple saw an opportunity to manipulate and exploit an emotionally vulnerable Regina.
