Despise what Cora did to him he needed Regina for Bae. Before the (scared the hell out of me) kiss happen in the pawn shop Cora said, that they can both have their children. He would not need Regina anymore and she give hime the Orb for not interfering with her family reunion plans. So I think that Rumple visits Cora after she give birth to Regina and offer her more power and knowledge that she can get her daughter to be queen. I hope we will see the scene when Rumple hold Regina and for a short moment thinking that she could be his little princess if Cora didn’t choose power over love and then trying to forget that and knew that he has to make her his own little monster. (Robert could definitely play this and know I will love this scene, begore they air it, like I know the same with baby bae and rumple)
