Fern yanked her tote onto her shoulder when the boy started laughing, positive he was aiming it at her. But then she realized it was about Cuthbert/Cutty/Whatever. In that case -

HAHAHAHAHAHA

So her laughing was a little forced, and some of it might have sounded more like sobs (nearly being devoured alive by the squid and then being laughed at was emotionally scarring, okay?), but after everything that nasty Slytherin had done to her, it felt good to be the one poking fun. She almost wished Cuthbert was there, just so he could see what it felt like. Almost.

By the time she finished laughing, the Hufflepuff was back in her chair and feeling much more cordial towards the small Ravenclaw. "Hey. What's your name, anyway?" ... not that she was actually going to call him by it. He deserved a name that would rival Lake Girl.
