There are a bunch of pictures of the filming of this scene. Emma walks behind David’s truck and slips and then Mary runs over and then David run over to help her up and see if she is okay and then Emma storms away from them. It is sort of like i can’t talk to the two of you right now. I think it is Ep 21 because Emma is wearing that weird skirt from the scene when she visits Regina and tells Regina that she is going to leave town and gets the turnover. I think this is sort of how Emma is going to feel once she knows that they are her parents and they know she knows. Emma is going to be angry and upset and not really know how to deal with the situation.
