Sierra sat quietly in her seat while her head moved from classmate to classmate. Most of them sounded like walking dictionaries. Either that, or they were all just really great at using big and unusual words. Maybe they were all related to Kurumi Hollingberry in some way, too...

Sierra spotted her brother seated across the classroom. They hadn't said much to one another in months, but their twelfth birthday was coming up soon, so she guessed it would be nice to try and reconnect with him. Coming to Hogwarts had nearly killed any closeness they'd once had. Well...it wasn't her fault he'd gone and gotten himself sorted into Hufflepuff.

She turned her attention to Lafay and raised her hand. "Poisons are substances that can be deadly or make you seriously ill, but they have other uses, too," she said. She lowered her hand before saying anything else. "Some poisons can be used to control insects and weeds or as an antidote to other poisons--like a snake's venom."

...and on that note, she might have given a few nearby Hufflepuffs a wicked-looking smile.
