In Book 15 of The Odyssey, how has Telemachus grown as a result of his own odyssey?

We are shown a Telemachus who has definitely grown up a
lot in Book 15. Consider what he manages to achieve. He shows himself responsive to
communication from the gods, he remains resolute on doing what the gods have asked him
to do, even when he knows that he will upset Nestor by not greeting him formally, he
shows compassion by giving refuge to Theoclymenus and taking him with him to Ithaca and
then he also manages to avoid the ambush of the suitors when he returns to Ithaca by
travelling at night. We certainly see a Telemachus who is developing very quickly into a
brave young man in his own right, and we can see the qualities of his father in him in
Book 15.
