The Sound of Drums AU:
The Doctor, Martha and Jack watched as Harold Saxon gloated at the sight of Martha's family being manhandled by goons.
Where's Lee Harvey Oswald when you really need him, Jack thought mordantly. Turning to the Doctor, he said, "I could sneak up on him and snap his neck."
To Jack's surprise and disgust, the Doctor merely said, "I'm not here to kill the Master; I'm here to save him."
The hell you are, thought Jack. I've read the UNIT files, I know exactly who and what the Master is, and I'll be damned if I let him endanger this planet because of your misguided sentimentality.
Springing into action, Jack quickly pulled out his revolver and fired three shots into the Master's head, utterly destroying the Time Lord's brain pan. Regenerate from that, ya bastard, Jack thought gleefully.
Then he promptly cold-cocked the Doctor, grabbed Martha, and teleported all three of them back to the Hub before the security detail had time to react.
