Cosette blinked. Had he just called her a mouse? She raised her eyebrows slightly, her eyes watching him incredulously for a moment before shaking her head. "I sure hope you're not trying to earn points with me, because that would have just lost you several." She was honestly surprised by her own words, she wasn't terribly outspoken. Not anymore, at least.
She heard him as he told her he could help her think of something, then heard his dinner invite. She'd dreamed of being invited on a date with Sirius many times but it couldn't happen. She was actually almost offended by it now. He'd just used her to break up with someone and now he was asking her on a date? "And end up like her in a couple of weeks?" she asked, pointing in the direction the other girl had left in. She shook her head. "I don't think so," she added, opening her book once more.
