“Keep your eyes open, Fireheart. Keep your ears pricked. Keep looking behind you. Because one day I'll find you, and then you'll be crowfood.”

“Is this one of those keep-your-friends-close-and-your-enemies-closer things?""I though it was keep your friends close so you have someone to drive the car when you sneak over to your enemy's house at night and throw up in his mailbox.”

“Keep an open mind, but no so open that your brains fall out”

“Listeners, that brings us to the end of another Potterwatch. We don’t know when it will be possible to broadcast again, but you can be sure we shall be back. Keep twiddling those dials: the next password will be ‘Mad-Eye.’ Keep each other safe. Keep faith. Good night.”
