Harry was in a bit of a frenzy. He had spent the intervening days since the memorial practically curled up in the foetal position, with the curtains closed and the lights off. He had eaten only when Ron pushed food under the door, and lit his wand to check his journal only when the inner turmoil became just too much to bear. He did his best to translate his true and sincere regret to Albus, but he thought he succeeded only in curbing the very edge of his son's anger, if that. He did not know how he could do better, or how to make it right with Lilu or Jamie either. After several days he was no closer to the answer, and the room really was starting to smell like something had died in there, but he found he couldn't bring himself to care about such trivial things.
But then Ginny was suddenly back..
His emotions went from rock bottom, to sky high, to all over the place within the span of a few minutes. He was glad beyond anything that LIlu had gone to find her mum - he was not in any state to do so himself, at the moment. The first thing he did was get up and take a shower, after which he felt more alive than he thought he had done in weeks, let alone days. Then he opened the door and the windows in his room and went into a cleaning frenzy. And it was literally a frenzy, with sheets and pillowcases and dirty clothes and plates zooming around each other in the air while he scoured everything with the strongest anti-baby-sick spells he knew. There was no sick, of course, but it did the same job.
The bed was made properly and the clothes clean if not folded, and he was still a little wild eyed and tousel-haired, when he heard the voice calling from downstairs. He froze, looking around as though he might see a foul-smelling sock right in the middle of his pristine carpet. "Keep it together, Harry," he muttered to himself. "Just... keep it together." HIs wife needed him. His wife. Not the young girl who would eventually become his wife.
He raced down the stairs, apologies and explanations and professions of his undying love running in parallel through his mind as he tried to figure out what he would say. When he saw her, however, stuck in the doorframe and looking for all the world like the bride figurine on top of the world's most pretentious wedding cake, all the words vanished. He burst out laughing, tears of mirth coming to his eyes as he almost collapsed against the wall in his efforts to get to her.
