I never got why the Council didn't decide to send more than Qui-Gon and Obi-Wan to investigate and capture Darth Maul. We know Qui-Gon (correctly) believed that he was a Sith Lord, and that it concerned the council. So why not send some (or all) the council members to go to Naboo? Can you imagine Maul opening the door and seeing not just Qui-Gon and Obi-Wan, but also Yoda, Windu, Ki-Adi, etc? It's not like the council had anything better to do, as they all were present on Coruscant and visited Naboo after the battle. Why didn't the Jedi take more action? You could say overconfidence, but this seems like common sense. Did they not believe Qui-Gon? No doubt he probably survives if they sent more help.
