Rose couldn't help the way her lips formed a bow and her eyebrows went up in surprise. He didn't seem like a stoner, really. He laughed a lot, sure, and he was goofy, but...he was smart. Stoners, especially at her school, weren't the smart people. "Oh. I wouldn't have guessed, honestly." A frown formed between her eyebrows, though it didn't reach her lips.
"I wouldn't have been able to tell, no. I mean, it's all your business, Mal." She felt so square at that particular moment, really, and her heart fell to her feet. Cursing was one thing. Even maybe having a beer was another, but she'd never ever considered drugs. She wasn't so backwards as to think they were the devil, but she wasn't about to try them. She hoped he wouldn't ask, but she was entering entirely new territory now.
