It was May, just after the annual commemoration of the Battle of Hogwarts – the fourth held already. Maybe that was why the memories and the trauma seemed so fresh, if they could be triggered by Harry's little godson – now only just four and on the cusp of Muggle primary school age – innocuously asking a science question. Her natural gifts as a student easily making her a natural teacher, Hermione was trying to improvise the inquiry into a lesson. Casting her brown eyes about, she finally seized upon a potted plant that Andromeda had set in the window and went to fetch it. "For example, the stem of this plant has water flowing through it. Your granny's plants need water inside of them to live just as we need blood in our bodies to live."
