I agree that I don’t think Charming would have left his mother to die. However we still don’t know what inspired Charming to leave when he did. Everyone assumes that it was because of Snow but that does not really make sense…The last time he and Snow had had contact before he decided to leave she had basically broken his heart and told him she did not love him. He has not spoken to Red yet so he hasn’t realized that she was lying to protect him. I can personally testify that men are really dense when it comes to that sort of thing, fictional or otherwise. He knew that his mother would be killed…I’m wondering if he got the courage to leave because somehow his mother got a message to him that she had somehow gone into hiding and she was safe. I would personally love it if Rumple had something to do with ensuring his mother’s safety. That would not surprize me in the least though for that to happen I think Charming would have had to have found his mother before he imprisoned him…curiously I don’t think he knows about the dagger…Slo many theories that could be spun about this…
