A week ago her answer would have been a simple ‘NO’, but fighting side by side with Dawn; watching her wield a sword, it had been a turning a point. She had promised to stop protecting her from the world and start showing it to her, and fighting evil was a part of their world.

Honestly, she’s surprised that her sister agreed so fast. Last time she asked, she’d been shot down practically before the question had even left her mouth. She wasn’t about to question Buffy’s change of heart, though; there would be no looking gift horses in the mouth for Dawn Summers today, no siree.
