Odysseus' men suspect that the contents of his bag is gold, so they open it to find that it is bad winds that send them back.
Odysseus needs to face a fear and go to the underworld to sacrifice a ram.
Odysseus finds himself at the island of the Phoenicians and is praised, so he gets a boat to travel back to Ithaca.
He returns to find that suitors are trying to win over Penelope, his wife, and take his kingdom.
Odysseus shows how he has changed by not immediately trying to harm the suitors, but by disguising himself as one of them . He accepts help from his servants and his son, which he wouldn't have done before.
Odysseus is tested with the suitors on a task that only he can do, string his bow and shoot an arrow cleanly through the holes on the handles of 12 axes. After completing that task, he then needs to prove his knowledge of something that only he and his wife would know, their bed.
