"I never saw Sarah again. I think I've managed to help some people in Congress - do some good. Less than I'd have liked, but more than I feared. To this day I still don't know if Sarah was real that night or just a product of my broken heart. But Sarah, if you are alive, and it was you that night, here for one last moment of sweetness before going back out to try and make things better in the world... I can only say, keep fighting.

I can only say, keep fighting. And God be with you. I love you."

"Ever the sun traces it's path from horizon to horizon, and ever the moon follows, and ever the days roll past without care for the lives they grind away, one by one. Try though as they might, no being escapes death forever, not even the rich or powerful. To all, there is an end."--Brom
