The big oak doors that were in the ballroom were too fancy to have cracks at the bottom. She stayed a mouse and, when she didn't see anyone in the room, she became curious. She sniffed the air around her. There was a familiar sent in the air. She smelt James and Sirius's colognes mixed together. She wrinkled her nose at the scent. She scuttled around the edge of the room, to avoid them seeing her. It was not a good sign that she didn't see them, but could smell them. She knew they couldn't all be smart enough to know how to use the invisibility charm on themselves. She waited underneath the Professor Roland's desk until there was a true sign the boys were there. She saw it soon enough, when the door creaked open, she ran towards the door, hoping to make it outside. She barley made it and was now on a wooden step outside. The night was clear and a full moon shone overhead, giving everything a silvery look. She found a place to hide and turned into am owl, so she could see everything that was going on. She heard some mumbling as she was soaring around the grounds, and finally saw James, Sirius, and Peter appear out of thin air. There was a cloak in James's hand. It was an invisibility cloak, she should have known. They weren't very common, and was probably a family heirloom of the Potter family. She watched the boys tentatively and perched in a tree. She saw James, Sirius, and Peter turn into animals. James was a stag, Sirius a dog, and Peter a rat. They walked to the whomping willow, which Gabrielle remembered was planted there when she first came to Hogwarts. She thought it was a bad idea to plant it there because it was a tree all right, but it was a tree that hit you back. They were standing as close as they could to the trunk of the tree without being hit by it. She saw Peter scuttle to the trunk of the tree; it didn't hit him because he was so small. Gabrielle saw him touch a knot on the tree and it froze in the position it was in last. James and Sirius followed Peter to a trap door near the knot of the tree. Sirius managed to open the trap door with his nose and Gabrielle followed after them as soon as she felt safe. She swooped down to the ground and in one smooth movement she turned into a white horse with a blonde main, and a tiara shaped golden patch of fur on her head that was there because of the costume she was wearing. She galloped to the trap door and entered a damp tunnel, but was forced to turn back when she heard steps coming her way. She was gone in a swoosh of her tail and galloped towards the forbidden forest, which was right outside the school grounds, and not far from the whomping willow. Once she found a hiding place, she saw James, Sirius and Peter getting out of the tunnel, still in their animal forms. She wondered why they even came here. Then, without warning, she saw a werewolf in a torn up school uniform come out of the tunnel. She put two and two together. Lupin is a Werewolf!
