Watching them walk past, Willow and Xander on either side of Buffy – their easy camaraderie making them look like a family – reminded Angelus of that first time Dru had become aware. She'd been in the center as well with one sister on either side. Glaring back with a frightened gaze, she'd wrapped her arms around them like a shield, scurrying her sisters down the street to the imagined safety of home and relations.
Family weakens you. Dru, in trying to save her sisters, had brought that lesson crashing down, destroying everything she'd loved. Now it was time to teach Buffy.
