'She's an impossibility, she shouldn't be alive but she is. Her people died long before the Timelords did and yet she live. She breaths she moves, she walks among the universe'
Angel is someone who shouldn't be alive, who the universe shouldn't have even heard of. Her people existed long before the Timelords and were wiped out a few years before the Timelords were. She's the last of her kind just like him and that's what makes them perfect for each other .
