Ginny had seen the effects of Roxy's chocolates on Oliver Wood and new better than to try them. But biscuits? Chocolate chip biscuits couldn't possibly be harmful. She laughed to herself over Professor Lupin's note, then helped herself to one, carefully flicking off the bits of charred biscuit from the ones beneath that were stuck to it. It tasted a charred anyway, and off somehow. Roxy definitely wasn't using her mum's recipe! Probably the House Elves gave her wrong instructions as a joke or something. She finished chewing and swallowed, despite the odd flavor, then noticed her brother talking to some people and ... wait a second, was that Snape? He wasn't popcorn anymore? Did Harry know? She thought she'd probably better talk this over with Ron.
