Jack paused for a brief moment. "You and I both know the Doctor can't be everywhere, every time. When someone invades, someone has to be there to protect humanity."

He crossed his arms, looking serious a moment. "Do you really think I would abuse that power?"

Jack snickered a little. "But it's just one word, I can hardly help it if it gets a rise out of people."
