Sirius has just escaped Azkaban after twelve long years of being stuck in there. You and him were real close, so close that you were dating and engaged before he was throne in Azkaban.

You were pregnant at the time and now your little one has grown up and they are in their second year of Hogwarts.

As soon as Sirius escaped, he set off to find you and now he stands, hidden as he watches you move about your day.
