Question: Why do Anakin and Qui-gon have to cover up the fact that it's Anakin's pod they want him to race? Anakin says, "You could make them think it's yours" (or something like that), and Qui-gon later says that he acquired the pod in a game of chance. Why the deception? What does Watto care, who built the pod?
Question: Obi-wan ordered the people on the ship to "send no reply" when the cries for help were being received from Naboo ("It sounds like bait, to establish a connection trace," he explained). That being the case, how did Darth Maul know they were on Tattoine? Darth Sidious even asked him, "Are you sure your trace is correct?" or something like that.
Question: Why does the Jedi council decide against training Anakin? One thing is that Yoda senses much fear in him, and that he is past the standard age for training, but with his power level you would think it wiser NOT to have him running around like a loose cannon, developing his powers in all sorts of directions, not to mention the risk of him being recruited by Dark Jedi.
Question: Is Palpatine's identity a spoiler? The Episode IV-VI movies never mention the Emperor's name. In Episodes I-III, we can guess that Darth Sidious will be the emperor, but what about Chancellor Palpatine? If the audience didn't know that he was Sidious, the impact of the reveal would be far different than if they did.
