Before Hermione could open her mouth –the way it looked like she was going to —Theo cut her off. "Neville told us Hermione was in the girl’s washroom, and that she’d been in there all evening after some row earlier. If that was true, she wouldn’t have known about the troll and would have been in danger. So, since it was on the way to our dorms, we were planning to just pop in and give her a quick warning. Neville was worried, so he came with us. He was going to walk back with her —safety in numbers and whatnot. But the troll was already here by the time we got here so, we just did what we could. We didn’t think we’d actually manage to beat it. But it’s not like we had a spare moment to just fetch a teacher." He lay the facts out simply, doing his best to keep everyone out of trouble and keep the facts as straight as possible.
