If somebody had told her at the beginning of the school term that she'd be creeping in the dark halls of Hogwarts in the middle of the night and breaking rules... with her sister??? For the fun of it? Parvati would've said it was ridiculous. Padma didn't break rules.
But here they were.
It was all quite surreal.
They rounded a corner and Parvati held out her arm to block Padma from going further.
"Mrs Norris," she hissed.
Sure enough, Flich's cat was sitting in the middle of the hall, lazily licking her paw. If Mrs Norris saw them, their evening's fun would be cut short very soon.
"What should we do?" she asked. "Take another route?"
This hall was the shortest way to the Library, the easiest path to take. Going around the cat would take up more time and raise the chances of them being seen by somebody else.
