ANTONIO: Let’s all sink wi’ th’ king.
SEBASTIAN: Let’s take leave of him.

– William Shakespeare

The Tempest, Act 1, Scene 1. This is one of the first signs that all might not be rosy with the royal party. Sebastian shows a lack of loyalty to his brother Alonso, King of Naples. He is ready to abandon him to save his own skin and suggests that Antonio do the same. This passage is foreshadowing of Antonio’s and Sebastian’s treachery later on the island.
