Penelope reveals her crafty side when she seemingly dismisses Odysseus' request for a bed with a simple command for Eurykleia disguised as a test for Odysseus. This, and her tricking the suitors for three years with the burial shroud shows not only her cunning, but also compatibility with Odysseus, the master tactician.
The reunion with Laertes is somewhat anticlimatic, why does Odysseus contine to lie to yet another person, even when his task of giving the suitors what they deserve is completed?
Laertes shows his sorrow by sifting "handfuls of sunburnt dust" over his head, the way ancient Greeks grieve is heartbreaking.
How did the news of the suitors slaying spread so fast? It couldn't have been Dolios or his sons because they welcomed Odysseus like loyal men.
When Athena and Zeus are discussing, Athena mentions something about "blot[ing] out the memories of the sons and brothers slain". And yet later on, she allows and even empowers Laertes, for Eupeithes, Antinoo's father, to be speared. Only afterwards does Athena appear to scatter the mob. And with that, The Odyssey concludes.
