You could also cut that scene imo. There is little pay off to it and the point of the scene is really the following line, that he could stop people from dying. That’s what hooked Anakin, because the driving plot at that point is really his fear of the loss of Padame. As his dreams tend to come true, this is what drives him right down to the final moment he’s staring off at Padame across buildings. Breaking at that moment and deciding to stop Mace. It was made that moment imo, not when he was there and cutting his arm off. He wasn’t supposed to be there.
