Neville grinned a little nervously. He liked the twins, although he was a bit intimidated by their cleverness and evident magical skill. He didn't want to be made a target for any of their experiments, which ranged from the humiliating to the downright dangerous. "What's this we hear about you shacking up with our little sister, Longbottom?" one of them demanded. He was smiling, but in the sort of way that suggested teasing on the very edge of sincerity. Added to this, Neville had no idea which one of them was which, and hoped desperately that he didn't get caught out.
He shrugged, trying to make it look as though he was merely standing behind Ginny, not using her as a human shield. "Like I have any choice, with all these chaperones," he said.
