"That one works too," he said quickly. "You can add it and make it an even five hundred lines then." Not that he really wanted to sit here and watch her write out 500 lines. He could entertain himself by watching the map and laughing over which students he spotted tangled together, but it just wasn't the same as it used to be.

Sirius returned to his desk and fiddles with a corner of the map. "Tell me, Miss Bones, how did Miss Weasley come by this?" he asked.
