"As to the second part of our bargain," She continued, "Well you still failed to kill me. So my ninjas are not yours. But they will be gone from your city before the dawn. I promise on my honor."
That was the last George heard from her, until they bumped into each other outside the music store twenty five years later. They had been arch enemies for years, yet never knew they liked the same 80s synth-pop. While George still protected the city most evenings, Nina had given up on the world domination, and instead went back to school for her masters in interior design. After dating for three years, George was finally ready to ask her to marry him.
At the moment however, he just wished she was there. And that she still had some of those ninjas.
