Hogwarts bush

one cold winter night, Hermione,harry and Ron are walking into the Hall with Harry's invisibility cloak. then they start to whisper Harry: are you sure he went this way? I mean, we can't risk getting caught by Snape..... Hermione: you are right, but I'm pretty sure that he isn't here right now. he should be at the dungeons. Ron just stays quiet,that's unusual , him, normally he is talking, but right now,he is to nervous to talk (you continue!)
