Summary: Some mistakes are bigger than others and even Angel's flee when a good man cries.
The Doctor stared at the tombstone which now read both Rory and Amelia Pond's names across it's face and he knew he couldn't get them back. Another paradox would be the only way to get them free and that would shatter the time-space continuum.
A deep rage settled in his bones, he'd never truly hated Weeping Angels before, they were simply living out their lives and the way they killed was so gentle as to almost be beautiful in it's simplicity. Yet, he'd never actually had one of his companions, his friends, his family taken from him by one of them.
He stood smoothly and stared the Angel in the face. "Listen to this. I may not be able to permanently hurt you like this, I may not be able to destroy you myself, and I may be forced to admit I cannot save them but what you just did. Oh what you just did... You don't truly understand do you? Those two people you just killed, they were my family. Because of you I will find a way to rid the universe of you and your kind. Because of you what just happened to your race in nineteen thirties new york is gonna look like a bright summer day before I'm done," with that he turned and walked back through the door of the Tardis, knowing River would keep her eye on the angel till she was inside. Even if she didn't, he was beyond pissed. Demons Run would be playful compared to what he could do now, he was one thousand years old and that lent a lot of room to see all manners of horror one could inflict.
