Aqua droid s search far and wide , forcing Lee - Char and Ahsoka to keep on moving . In order to restore the peace between the Mon Calamari and the Quarren , the prince decides to free the prisoners , whose numbers would overpower their captors , and draw the Quarren back to their side . For this purpose , Lee - Char and Ahsoka follow a column of prisoners to an underwater cave used as a prison camp , where Lee - Char addresses his people to restore their courage . But an aqua droid spots them and they are surrounded by the guards , but Lee - Char demands an audience with their commanders , which is granted . Meanwhile , Nossor Ri expresses his growing doubts about this war and the planned eradication of the prince to Count Dooku , and has to learn to his consternation that Tamson has brought his own troops to garrison the occupied city instead of allowing the Quarren to rebuild . Tamson returns to interrogate the prisoners and attempts to force them to talk by biting a tiny hole into Padmé ’ s helmet , allowing her suit to fill up with water . But then he learns that Lee - Char has been apprehended and orders the droid troops to take him and Ahsoka to the Mon Calamari throne room , where he ( as he gloats at a startled Ri ) would receive the prince as the planet ’ s new ruler , as per an agreement between himself and Dooku . However , Lee - Char denounces him face - to - face , boldly challenging Tamson ’ s claim of leadership over both Mon Calamari and Quarren , and appeals to Nossor Ri ’ s friendship with his late father and the tense but respectful relationship the Mon Calamari and Quarren had enjoyed under his rule . Spiteful , Tamson orders the prince to be publicly executed . As soon as Tamson and Ri have left , Anakin and Fisto remove the water from Padmé ’ s helmet with the Force , and Jar Jar uses his saliva to seal the puncture , saving her from drowning . Shortly afterwards , the prisoners are all taken to witness the prince ’ s execution , but as the preparations are underway , Ri , who has finally had a change of heart , secretly communicates his people ’ s support to Ackbar . At the critical moment Ri saves Lee - Char , and the Quarren , Mon Cala , Jedi , Gungan s and clones unite under the prince , engaging the Separatist droid forces in battle . Lee - Char prevents Tamson , who cruelly confesses to be the one who killed his father , from fleeing , engages him , and kills him with one of his own explosive knives . After restoring the peace , Lee - Char , now recognized by both Mon Calamari and Quarren , is crowned the new king .
