Quote 4
KENT
[…] There is division,
Although as yet the face of it be covered
With mutual cunning, 'twixt Albany and Cornwall,
Who have—as who have not, that their great stars
Throned and set high?
[…]
But true it is, from France there comes a power
Into this scattered kingdom, who already,
Wise in our negligence, have secret feet
In some of our best ports and are at point
To show their open banner. (3.1.23-27; 34-38)
Although Lear had hoped that division of his kingdom would prevent strife and result in unity, Lear's decision has clearly resulted in conflict and disorder. Here, Kent reveals that civil war is brewing between Albany and Cornwall and France is preparing to invade.
Quote 5
KENT
Thy youngest daughter does not love thee least,
Nor are those empty-hearted whose low sound
Reverb no hollowness.
KING LEAR
Kent, on thy life, no more.
KENT
My life I never held but as a pawn
To wage against thy enemies; nor fear to lose
it,
Thy safety being the motive.
KING LEAR
Out of my sight! (1.1.171-179)
Kent is the only one who stands up to Lear after the king disowns Cordelia for refusing to flatter Lear. When Kent points out that Cordelia (not Goneril and Regan) loves Lear the most, he's told to shut his mouth, or else. But Kent won't be silenced—he's worried about Lear's safety so he speaks what's on his mind. His reward for being so blunt? Lear banishes him, of course.
Quote 6
KENT
Sir, 'tis my occupation to be plain:
I have seen better faces in my time
Than stands on any shoulder that I see
Before me now at this instant. (2.2.96-99)
Ooh, burn! After Kent strikes Oswald (because he doesn't like Oswald's face), he explains to Cornwall that it's just his personality to be blunt ("plain"), which is why he's being honest with Cornwall now when he says that he doesn't like the looks of Cornwall's face either. (What? Who says Shakespeare can't indulge himself by writing a little trash talk into his scenes?)
For Kent, being completely honest and speaking the truth is a matter of pride, even if his big mouth gets him into trouble. So, even if we fault Kent for being so ridiculously loyal to King Lear, we've got to give him props for being so truthful.
