In Book 20 of the Odyssey, the omens, dreams, and oozing
of blood from the suitor's mouth portend the coming clash between Odysseus and the
suitors, when he will kill them all for disrespecting his wife and son and the honor of
his house by killing all of his beasts, eating all of his food, ruining his home, and
trying to marry his wife. Odysseus returns home and stays in disguise to see what has
been going on in his absence. He has his patron Athena in his corner, and his son
Telemachus is ready to kill all the suitors himself, if need be. Check out the study
