LILY AND THE PORTRAIT:
Portraits could only mimic their real counterparts, even the headmaster portraits that were specially trained to guide Hogwarts’ future generations. Severus had no such time in his single year as Headmaster—and yet, his portrait seemed real enough to befriend. She first found him in a oft-empty frame by the armor gallery and tried to show Al, but Al said that they already met once, and they didn’t get past introductions and “Your father named you what?”
She bore the old headmaster’s sneers better than her brothers, and he was kinder to her, in his own way. She found that if she brought her Potions homework and sat underneath the frame, he would ridicule her mistakes as she worked but slowly enough for her to correct each of them. In her sixth year, after showing him her O in Potions, he told her where to find his old textbook.
On her last day of Hogwarts, she knocked next to the frame. Slowly, one of his eyes opened, like a serpent awoken from its slumber.
“Thank you, Professor.”
His lip curled upwards. She sensed some pride. “You are welcome. You were an excellent pupil.” He paused momentarily. "Miss Potter."
If her father were listening, he’d have thought it strange, for it would have been the first time that he heard his last name uttered in that voice without disdain.
