Kent, sir, the banished Kent, who in disguise
Followed his enemy king, and did him service
Improper for a slave.

– William Shakespeare

King Lear, Act 5, Scene 3. Edgar reveals to Albany how Kent disguised himself as the servant Caius so that he could continue to serve Lear, even though the King had banished him. This shows Kent’s great loyalty to his "enemy king" and his campacity for forgiveness.
