Be Kent unmannerly
When Lear is mad.

– William Shakespeare

King Lear, Act 1, Scene 1. Kent tells Lear that he must be rude when Lear is acting madly. For Kent loyalty is not about being a yes man, but rather doing the right thing and speaking the truth to his King, whether he likes it or not. He is the only person in the court to defend Cordelia and the only one, apart from the Fool, who has the courage to challenge the King when he is wrong.
