"Alexa?" Sirius asked sleepily, walking into the common room. He had been asleep when he'd suddenly felt the need to walk downstairs.
"Yes?" she asked, wiping her eyes quickly and burying herself deeper in her blanket.
Sirius sat next to her. "You don't need to hide your tears from me, you know."
She nodded vaguely.
"And you can tell me what's wrong," he hinted.
She sighed, leaning against him. "My foster father died," she said quietly. "And all of us kids are being moved to different homes. Only, I'm in a bad position, because only my foster parents, and the social worker in charge of me know about me being a witch. And the ministry doesn't want too many muggles to find out. They might be sending me to an orphanage here in the wizarding world."
Sirius turned to look at the beautiful girl next to him. She'd changed in the five years he'd known her. She'd gotten taller, but not much. Her curly black hair had grown long, but she'd recently cut it, so that the curls just sort of flew about everywhere. He thought it was almost criminal that she could be this beautiful.
"I'm sorry," was all he could think to say.
"I'm fifteen!" she cried. "I don't want to go to an orphanage! I don't think I could bear it! I-"
"Stay with me," Sirius blurted out before he could stop himself.
"W-what?" she sputtered, turning to face him. "You live with the Potters."
"I can't stay there forever," he told her, matter-of-factly. "I was thinking about getting a flat. you can stay there with me if you'd like."
She looked thoughtful for a second, before her face spread into a huge grin. "I'd love that!" she exclaimed before hugging him tightly.
Until then, Sirius had decided living on his own would be great. He couldn't think of anything better.
Except for this.
