Alonso has washed up on shore with Antonio, Sebastian, Gonzalo, and attendant lords. Gonzalo tells everyone that they can balance their sorrow with comfort—at least they've survived the terrible shipwreck.
Antonio and Sebastian agree they will keep watch over the King while he sleeps, as they are not at all sleepy. They still wonder why everyone became sleepy.
Both come up with a plan to kill the sleeping kin since they are the only ones awake. Since Alonso is the only one in the way of Sebastian and the crown.
EQ: Is there more value in vengeance or virtue?
Ariel tells Gonzo about the other's plan and quickly wakes up to warn the king. The King wakes up and the excuse that Sebastian and Antonio say is that they heard lions and only drew their swords to protect the king.
King Alonso is freaked out by the possibility of lions and, not knowing Antonio and Sebastian's wicked plan, Alonso suggests they all leave the place at once to see if they can find his son.
There is more value in virtue because it doesn't cause more hatred. Virtue ends all arguments in a good way. Vengeance will create more problems causing hatred to be bred leading to a cycle of vengeance.
