You don't want Chuck McGill as your enemy. When Howard finally told Chuck that he doesn't trust his judgement and that he wants him to retire, it was clear that Chuck had no plans to bow out.

After taking some time to let the dust settle, Chuck messengers a letter to Howard, who mistakes the correspondence as a letter of resignation. Suffice it to say, it's anything but.

See how Howard responds to Chuck's bold threat in this talked about scene from Episode 9.
