She was 15. She was 15 when she realised that something had changed. Brittany became... different. Not in a bad way. If anything it was a gift, the powers that is. Not the responsibility that came with it. But still, she has to accept that she was the only one who could help. Or at least that what she thinks... (Brittana in the Buffy the Vampire Slayer universe) Also PS. This isn't a crossover just an AU so you don't need to know anything about the show this is based off :)
