Voldemort was truly gone because of Severus' intelligence and Harry's luck. Facing the crying child of 15months, Severus doesn't want to entrust him to anyone else. Taking a child into his care so soon after Lily's death and with little to provide for him...it appeared to be a disaster in the making. Seven years later and Dumbledore can no longer stand it and goes to check on the pair. Nothing could prepare him for what he finds.

And afterwards, to understand how it came to that point, I have taken the story back to the beginning in the second part to show the journey that brought them to that point.

The final section will express Harry's years at Hogwarts following a concluding one-shot to ultimately answer the question: Did Severus make a mistake in taking in Harry, or not?
