Good idea Gobalicious, and nice video Davnes.
Maybe Palpatine's shuttle arriving is the reason why Obi-Wan just leaves Anakin to burn? When the movie first came out, many disliked that Obi-Wan just left Anakin there to burn, and it still comes off as kind of cruel. But what if he saw Palpatine's ship arriving and he knew he had to get the hell out of there? The scene would need to be tweaked a little, but it might work.
