How does Telemachus take initiative in becoming mature throughout the book (use quotes)?

Homer's epic poem The Odyssey is really a story of two men's journeys. Most people know of Odysseus' journey home to Ithaca since he is the main character and the epic poem's namesake. But Odysseus' son, Telemachus, goes through his own journey to adulthood in the book. Throughout the story, readers see Telemachus transform from a worried boy into a brave man. A lot of Telemachus's journey is featured in the first four books of the epic poem, and these four books are often called the Telemachy for this reason. However, one must read the whole epic to see Telemachus's journey to complete maturity.
One instance of Telemachus's developing maturity occurs in the very first book of the epic when he decides to stand up to many unruly suitors who have taken over part of his family home. They are there to court his mother, Penelope, in hopes of marrying her and taking over the kingdom. Telemachus is "sitting among the suitors" (book 1, line 132) and watches them take over. He does nothing at first, as his "heart [is] obsessed with grief" (book 1, line 134). He is sad, he misses his father, and he appears hopeless. A bit later, Penelope attempts to push back against their advances. Telemachus decides to be brave and he tells his mother that he will handle them, saying: "Mother, go back to your quarters. . . . As for giving orders, men will see to that, but I most of all: I hold the reins of power in this house" (book 1, lines 408–414). He tells the suitors, "You must leave my palace! See to your feasting elsewhere" (book 1, lines 430–1).
Telemachus then becomes inspired to go out exploring to find news of his father, Odysseus. He travels from island to island and speaks with many of Odysseus's peers. When he speaks with a man named Menelaus, Menelaus tells Telemachus that he is becoming wise and brave. Menelaus says to him, "Not even an older man could speak and do as well. Your father's son you are" (book 4, lines 228–9). Comparing Telemachus to Odysseus says a lot about Menelaus's level of respect for Telemachus as a mature man; he is not a boy.When Odysseus finally returns home after twenty years away, Odysseus knows he must fight off the suitors who have been trying to take over his kingdom and marry his wife. Telemachus is ready to help him do this gruesome job, which shows Telemachus is braver and more mature than he was at the start of the epic poem. He no longer sits idly by. Instead, Telemachus is bold enough to criticize his father's plan and suggests other ways to fight the suitors. He says, "I'm hardly a flighty, weak-willed boy these days. . . . I think your last plan would gain us nothing. Reconsider, I urge you" (book 16, lines 343–7). The men go on to defeat the suitors and protect their reign over the kingdom of Ithaca.Telemachus's road to adulthood and full maturity is an interesting journey to follow.
