I think Regina is shocked when Gold says please and now we know that is because he knows and didn’t want to tell who Emma was. I guess we have to think that the Queen knows very little about Emma. She knows that Snow had a girl and that the child was put into a wardrobe and disappeared. I don’t think she knows anything about the child coming back when she is 28. She knows that the child is supposed to save everyone from the curse. She doesn’t know that the child came to the real world.
I wonder why Rumpel told Regina about Emma at all? I just don’t know about his character. I guess he is just doing whatever seems fun at the moment. Though at the same time i think he has some sort of agenda. It is just so odd. At times it seems like he is working with Emma to try and get rid of the queen and yet at other times he seems to have no interest in her at all and just be pushing the queen away so that he can do whatever he wants without her bothering him.
