Who told Penelope that Odysseus came back to claim his land and slain all the wooers?

In Homer's "Odyssey," it is Telemachus, Odysseus's son, who informs Penelope of Odysseus's return. After slaying the suitors who have been vying for Penelope's hand, Telemachus reveals his father's triumph and assures her that Odysseus has reclaimed his rightful place in their home. This revelation brings Penelope a mix of joy and disbelief, as she has been yearning for her husband's return for many years.
