It was midwinter, nearly Christmas, and the halls of Hogwarts were icy and empty, most of the students having left for the mid-year holidays to spend Christmas with their family. But you had stayed. A while back, Professor McGonagall had asked you a special favour, to stay back and help tutor a fellow student in your transfiguration class, because he had been struggling with his spells. And you had agreed. You were one of the top students in your class, becuase you had studied and worked hard to memorise your spells and improve your skills. Now, you walk through the chilly halls of Hogwarts towards a small alcove by one of the larger windows, in a particularly secluded part of the school, a place where Professor McGonagall said Albus Potter was supposed to meet you. He's standing there, his breath misting in the cold air, shuffling his feet, a wand in his right hand, and a book of charms in his left hand. You know theres a number of empty classrooms nearby which Professor McGonagall had said were free for you to use. When Al sees you, he gives a small halfhearted smile.
