The Master and The Doctor in “The Deadly Assassin”

Doctor, my congratulations, you're just in time for the end!

You're insane! You're insane, do you hear me? You're releasing a force that nothing can stop!

Take the rod. You could take it with you to your grave, except that none of you will need a grave!

If you undo that, you'll die as surely as any of us!

You can do better than that, Doctor. Even in extremis, I wear the Sash of Rassilon!

Yes! And the president was wearing it when he was shot down! The sash won't protect you! It's damaged!

You lie!
