The boy must be at least twenty years old at the time of the poem’s action, and he is physically an adult, full grown and handsome. But he struggles to grow to psychological maturity, to become man enough to help his father defeat the suitors.
This passage articulates the central developmental thesis: Telemachos’ arc is one of psychological rather than physical maturation, specifically the acquisition of adult masculinity modeled through encounters with surrogate father-figures.
