In the tempest is Antonio friends with the king of Naples?

In Shakespeare's "The Tempest," Antonio is not friends with the King of Naples, Alonso. Instead, he betrays his brother, Prospero, and aids in the usurpation of Prospero's dukedom. While Alonso is initially unaware of Antonio's treachery, the two are not allies; their relationship is complicated by betrayal and power struggles. Ultimately, the play explores themes of reconciliation and forgiveness, particularly between Prospero and those who wronged him.
