Well...ummm. When they were at the door and it opened, and Darth Maul appeared I guess they could've ran away and left Padme to be slaughtered... that would give the Jedi a really good name. Obi-Wan had a pretty good reason to fight Maul... seeing as Maul killed his master and all...
And Dooku taunts Obi-Wan in Episode II's duel.
