Sirius laughed as he watched her expressions change to represent so many emotions one by one. It made him curious, as to how one person could feel so much in the course of a minute, and yet, it didn't surprise him at all. Walters was an interesting girl, so strange and foreign to him in so many ways, and yet, also so very similar in ways he knew not of yet. So, when she pulled out the map, he continued to grin. He knew she'd be curious about that, it was after all, a strange bit of parchment. He also knew she would never figure it out or how to use it, without him telling her. "Oh, yeah, it is, isn't it? Too bad for you I'm not telling. That's top secret, and I can't share it with you without dicussing the matter with James and Sirius first... it'd be going against their trust to do so, ya know?" She was pretty yes, but he wasn't about to blow his friendships for a girl.<br/><br/>He slid his chair a little closer to her and took the parchment from her hand, pocketing it in his robes. "And yes. Prongs." He nodded, confirming her question. "Just like how sometimes you call Lily that weird name, what was it? Beansprout or some other weird plant? How the hell did that come about, I'd like to know." He rolled his eyes, playfully, leaning towards her. "And she calls you Rowdy doesn't she? Because it's another term for when a person is being riley or unruly, yes? But then, you look more like a Ri-Ri, than than a Rowdy..."<br/><br/>Lily kept her face down, biting at her lower nip ever so nervously. Her stomach was doing jerks and leaps and she couldn't understand it. Popular and seventeen she may be, but she'd always had terrible luck with boys, especially the cute ones. The pimple ridden, dorky boys were the ones she was more friends with, because of her charms and potions skills, and her taking to just about anyone who was human who'd let her. She loved people, so long as they weren't bad, mean and nasty.<br/><br/>Very slowly, she moved her eyes to glance at him as he asked her that question he had asked her so many times before in the past. And very slowly, she pondered it, and then, for the first time, nodded her head. Just once, but it was a very clear nod. She couldn't speak she was so very anxious. Her hands were all tangled up in the hem of her skirt and she purposely reached one up to remove the hair from behind her ear, letting the red curtain fall to hide her face again, too embarassed of her own blush to show it.
