Being a guardian angel wasn't so bad, Buffy mused as she ghosted along behind one Gregory Callen, not that he knew that. He had no idea the best slayer there ever was, her and Sineya had settled that debate in the ring, was his, and only his, guardian angel. He also had no idea his name was Gregory, trauma from his mother's death scarred even that.
Being this particular agent's guardian angel was surprisingly easy after that scare with the drive-by. Buffy had even extended her protection to the others in his group. Technically it was breaking the rules but the way Buffy saw it saving them protected her charge in the long run. And he definitely needed it, jamming weapons, knocking bullets off course, slowing bomb timers just enough to ensure safety, tripping opponents with a well placed bit of trash.
Yet somehow, despite his ability to get in even greater amounts of trouble than Dawnie he was still easier to protect, and protect him she would, till his job was done. Till it was his time to rest, as it had been hers... before she'd accepted this job to save herself from boredom.
