Jennifer Penrose, that was her. She is punished for locking up Blossom by having appalling nightmares about B having been cut to pieces by glass while breaking out of the art room window.
I always thought it was a bit risky to just ask a junior to tell Blossom she was supposed to go to the art room -- how safe was it to assume that said junior didn't know who she was and wouldn't recognise her again, if asked?
I know we're told that the junior (can't remember who it was) doesn't know Jennifer's name and can't identify her, or even describe her, when asked, but how realistic is that at the CS? How big is the school when it's on St Briavel's?
I have a seven year old at a village school with just over 200 pupils, and he seems to know all, or virtually all, of them by name, or, if not by name, he knows them by sight, or that they're friends with X, or are Y's older sister, or played Mary in the nativity play, or dressed up as Pippi Longstocking for the last World Book day.
I would have said that in a boarding school an individual pupil would be even more likely to be able to recognise a random older girl?
