Mrs. Granger finds a stranger waiting for her when she gets home from work, yet she knows who the person is as they share physical traits with someone she knows. Disclaimer - I don't own Harry Potter. This is written for the Froday Flash Fiction challenge. Specifically, this was written for the monthly special for January 2022 where we were given a sentence to begin our stories with and this was the end result. Story utilizes my headcanon of Regulus being Hermione's biological father I've come to love.
