Book XV:
* Reveals Odysseus's identity: Telemachus finally tells Nestor and Menelaus that the beggar in their midst is actually Odysseus, his father. This revelation sets in motion the chain of events that will lead Odysseus home.
* Encourages Odysseus to visit Menelaus: He persuades Odysseus to stay with Menelaus for a while, knowing that Menelaus is a skilled storyteller who might know something about Odysseus's whereabouts.
* Expresses his own desire for home: Telemachus expresses his deep longing to return to Ithaca, foreshadowing his own journey home that will happen shortly after.
Book XVI:
* Embarks on his own journey: Telemachus sets sail for Ithaca, leaving Odysseus with Menelaus. This departure allows Odysseus to continue his own journey home independently.
* Sets the stage for Odysseus's return: Telemachus's departure makes it possible for Odysseus to return to Ithaca, as he knows that his son is no longer there and won't be an obstacle to his return.
Key Points:
* Telemachus doesn't offer direct advice to Odysseus in these books. His actions are more about providing opportunities and facilitating Odysseus's path home.
* Telemachus's own journey of self-discovery parallels Odysseus's journey. He gains confidence and independence by leaving home and navigating challenges, preparing him for his role as a future leader.
* Telemachus's actions contribute significantly to the overall plot of the *Odyssey*, driving the story forward and setting the stage for the dramatic events to come.
Essentially, Telemachus's actions in Books XV and XVI help move the plot of the *Odyssey* forward, setting the stage for Odysseus's return, and demonstrating Telemachus's growth as a character.
