Harry was woken by a sharp bang, jolting into the waking world - but he didn’t move, eyes shut and listening closely to his surroundings. Please, please let him be at home. Please, please let that have been Lily slamming the bathroom door shut behind her. Please let James cry out in annoyance, having been shoved to one side by his younger sister so she could use the bathroom first, and thus avoiding traipsing up another floor to their distinctly less pleasant second bathroom. Please, please,  please.
