The transition was worse than he expected (especially the nausea), but at least it was silent.  After taking a moment to gather his wits, he peered at his double.  His opposite was hunched over the main controls, speaking in a curiously silky voice.

“Amy, my sweet, furry, nearsighted Cricetulus barabensis, are you in position?”

Emphatic, high-pitched squeaks reverberated throughout the Tardis as a display translated her response.

“In Position … Weapon primed … Shut up.”

His laugh was engaging as it was disturbing.

“Rory, our lovely Amy is ready…  How are you bearing up?”

The roars filled the Tardis as the translation rolled across the screen.

“Queen’s party approaching… fusion reactor set to overload… shouldn’t someone your age be funnier?”

“My God, man… you’re going to assassinate the Queen?”

His opposite looked up at his newly revealed counterpart with a knowing, devilish smile.

“Silly alternate, assassinating the Queen is merely a charming side effect of obliterating London… care to watch?”
