2 observations on The Odyssey: nobility v servitude, and family reunions

Just two notes on The Odyssey today, both Odysseus and Telemachus have returned to Ithaca and they meet - O in disguise - and the rude farmhouse of the ever-loyal swineherd, Emmeus (?). After an evening of dining and drinking, E. tells his life story to O (I think) and reveals that he was a prince who was kidnapped and essentially sold into exile and slavery (reminds of Sansho the Bailiff, which I just saw) - so now we get it, the guy who's the truly loyal, selfless, devoted, asexual servant isn't really of the servile "class" at all but he's of noble birth: only the nobility know how to be truly servile and self-effacing. It's an ideal they hold so high that none but they can execute it. So this goes far beyond the loyal servants in, say, Shakespeare, who seem to have little purpose in life other than to prostrate themselves so that their "masters" can step on their backs. Homer went one big step further in his ideology: to be a true servant is to be ennobled, and vice versa. Second, what about the meet between Telemachus and Odysseus? I don't know if others agree but it seems to me a cold and unemotional reunion: O hasn't seen his son in 20 years (the timing doesn't seem exactly right as T behaves more like a teenager than a 20+, but no matter) and T has traveled around the Mediterranean just search of news of his father - but when they meet there's not a lot of tearful embracing and expression of emotion, it's just a recognition and, almost immediately, setting forth on a plan to clear out the suitors and reclaim Penelope and the seat of power. What's with this?
