Odysseus shoots Antinous with his bow and arrow when Antinous is distracted. The suitors are enraged by Odysseus's actions, believing that it was an unintended killing.
Weapons for the suitors!
Odysseus reveals to the suitors that he is the king of Ithaka who has finally returned home. The men are terror-stricken and beg for forgiveness, attempting to justify their actions and claiming that Antinous was the only immoral suitor. Odysseus dismisses their excuses.
The suitors combat against Odysseus, Telemachus, Eumaeus, and Philoetius, though the suitors are unarmed. Numerous suitors are killed.
During the battle, Melanthius secretly gets into Odysseus’s storeroom and brings out weapons for the suitors to use. When he goes back to get more, Eumaeus and Philoetius capture him.
Athena arrives on the scene, disguised as Mentor. However, she does not fight alongside Odysseus, but rather, spectates the battle and makes sure that Odysseus and Telemachus do not sustain major injuries. Ultimately, all of the suitors are killed. Odysseus only spares the bard and herald by Telemachus’s will.
Odysseus makes traitorous female slaves clean up the bloody mess and later puts them to death. On the contrary, the men dismember Melanthius’s body parts from his body. The castle is then purified with fumes.
