Belle regarding Rumples actions. As I wrote somewhere else on the forum Belle is so heartfelt and genuin. She doesn’t want anything bad to happen to anyone. But I don’t think she will be against them using magic to keep the enemy out, they do it to keep Cora and Hook out afterall, not to hurt Emma and Snow.
Belle comes from a land of magic, so I don't think she has many prejudges against the use of it, if its for a good purpose. And in the promo she is not standing next to the well when they, we might assume, see Emma and Snow are the ones that pop up. So she can't try and stop it then. But if she where there, I think she would try and stop Rumple when she saw innocents getting caught in the crossfire.
