Answer:
Penelope
Step-by-step explanation:
When Odysseus confronts the suitors, he kills every single one of them. He also gets rid of all the treacherous people who lived in his house. As Odysseus is putting his house back in order, Athena induces Penelope in a deep sleep. This means that Penelope sleeps throughout the massacre, and is only awaken to discover that her husband is back home.
