Neville & Luna
Neville hadn't actually intended on staying. He'd walked with Luna and some of the Gryffindor girls down to Hufflepuff - on high alert - with the intention of going back up to his dormitory afterwards to study, but then it had been so warm and comfortable that he'd ended up curled into a corner of one of the blanket rooms, his jacket and shoes tucked to one side and a blanket over his lap.
Luckily he had his bag with him, so studying wasn't entirely out of the question. He lit his wand for extra light, since reading still made him dizzy after a few minutes even in good conditions, and tried to focus on all the Charms theory he'd missed out on while he was in the Hospital Wing, and not on the new, all-too-real threat that apparently roamed the halls.
