Final answer:
Penelope is initially skeptical but becomes filled with joy and relief upon confirming that Odysseus has returned.
Step-by-step explanation:
When Eurycleia tells Penelope the news of Odysseus' return and the slaughter of the suitors, Penelope is initially skeptical and doesn't believe it. She tests Eurycleia by asking her to move their bed, which only Odysseus would know is impossible since he built it himself. When Eurycleia successfully moves the bed, Penelope is filled with joy and relief, and she finally accepts that Odysseus has indeed returned.
