The duel with Mace ends when Mace kicks Palpatine down and Palps loses his saber out the window. Did you read this as intentional because Anakin is about to arrive? Or was it a legitimate mistake? Also, what about his cowering like an old man directly after that? Of course the surrender a bit later is for Anakin's benefit, but what about when Anakin isn't there yet? I get the impression he wanted Mace to feel like he had won, so the events could play out like they did. Also, I find it curious that Mace's saber is lost out the same window a couple of minutes later. And they both simultaneously broke that window, perhaps both planning to throw each other out?
