Frodo Baggins [SEP] "The Return of the King"
Sam rescues Frodo from the Orcs. After a brief confrontation in which Frodo becomes enraged that Sam has taken the Ring, Sam restores the Ring to Frodo. The two of them, dressed in scavenged Orc-armour, set off for Mount Doom, trailed by Gollum. They witness the plains of Mordor empty at the approach of the Armies of the West. As the Ring gets closer to its master, Frodo becomes progressively weaker as its influence grows. When they run out of water, they leave all unnecessary baggage behind to travel light. As they reach Mount Doom, Gollum reappears and attacks Frodo, who beats him back.
