Забавный диалог между Дэвидом и Джоном:
"It's a sonic screwdriver," David explains.
"Sonic?" scoffs John, a grin shining through his attempt at mock disgust. "Who'd have sonic? Laser, mate, that's what you want."
"The Doctor wouldn't use laser."
"This is brilliant, then - the Master will win!"
"He won't win, John. He never wins."
"He will."
"Won't."
"Will."
