"Sirius?" Harry asked suddenly one evening at Number Twelve Grimmauld Place.
"Yes?" he said.
"Did you ever, before Azkaban I mean, did you ever, I mean…was there a ever a girl in your life?"
Sirius smiled sadly. "There was. Once."
Harry could sense that Sirius didn't want to talk about it, but he really wanted to know. "What happened?"
Sirius looked into Harry's eyes, and the sadness from being locked up in Azkaban for twelve years, and being utterly useless stuck in the childhood home he hates, was nothing. Absolutely nothing. She had obviously been very important to him.
"Her names was Alexandra," he said, looking away. He looked very distant, as if lost in another time.
He smiled at Harry and said, "Goodnight then," before walking away down the hall.
That was strange.
