Did You Know?
In the original script, the Graff did not murder the Seeker but instead sent her back to the Catacombs, whereupon the Captain set off the explosion to seal the caves (killing the Seeker in the process). Believing himself to be the prophecied survivor, the Graff - insane and hallucinating about past campaigns - then took an ammunition pouch from a supposedly dead guard. The Doctor would reveal himself at this stage while an explosion detonated, proclaiming the Graff's final end. See more
