Lily walked down the hall towards the library, pushing a stray lock of hair out of her face. She was trying to find books for her Muggle Studies project, and had no clue where to start. I can't believe it's only day two and we already have this much homework she sighed and hurried on. What she wanted to do was find muggle books, like muggle playwrights, and do a project on them, but didn't know if that would be allowed--or even if she could get her hands on them at Hogwarts.
She walked into the library and heading towards the back, then stopped and smirked when she saw a familiar head at a table. She weaved through and snuck behind him, putting her hand on his shoulder.
"Homework already, Siri?" she asked, smirking down at her twin.
Sirius grinned back. He was their brother, and for all that he hated the name, he was a Potter. He wouldn't betray his sibling.
"I suppose we must. He is our brother." He said to Lily. He turned to Neville, his grin getting bigger, if that was possible, and told him. "Full moon, I'm going to try the animagus transformation. I've been working on it for two years now."
"I am going to assume that you have no intention of registering this fact, much as your namesake didn't?"
Neville tried to maintain a severe look, but failed utterly. He laughed.
"You should have been in my house, Siri. Alright, how can I help, and Can I watch?"
"Where's the fun in telling? It'll be our little secret." Sirius told him, laughing a little too. "And I'm pretty much done, but thanks all the same. Lily and James are gonna come along, so of course you can too. Should be an adventure." Sirius finished, a twinkle in his eye. You always knew trouble was on the way when a Potter, especially this Potter, had that twinkle in their eye.
"It'll be full moon night, whenever the moon rises. We'll just have to go out early to be perfectly ready. We'll meet out in the Entrance Hall, and go from there." Sirius answered, smiling at the Slytherin comment. Sirius had his devious side, and he certainly wasn't ashamed to admit it.
