Hermione Jean Granger is locked out of Hogwarts castle. She doesn't remember how she got into this situation, all she really knows right now is that it's COLD. She frantically searches for her wand, her cloak pocket conspicuously empty. She curses into the air, frustrated and a little bit frightened. She glances around at the snow, hoping that she's dropped her wand nearby, panic slowly rising in her chest. Fighting to maintain some level of calm, she begins to retrace her steps, trying desperately to remember where she was. Finally she finds it, halfway across the grounds, half buried in the soft, powdery snow that began to accumulate an hour ago. Her cloak, unfortunately not her good thick winter one, is doing precious little to insulate her from the cold. She can feel her fingers going numb. Quickly, she casts a spell, a small blue flame appearing in her hand. As she runs toward the castle, a sudden gust of wind blows the flame from her hand, extinguishing it in a large snowdrift. She's almost at the door now. Her hand shaking with cold, she points the wand toward the door and mutters "Alohamora!" Much to her relief, because she can feel the numbing cold spreading through her limbs, the large door creaks open and she shuffles inside. The castle is by no means hot, so she won't warm up completely until she reaches the common room, where, no doubt, a huge fire is blazing in the fireplace. Thinking wistfully of that crackling fire to take her mind off her frozen fingers, she begins the long walk to her common room. Halfway there, heading down a corridor, she passes out and lands heavily on the cold stone floor.
