Chapter 1: The arrival of Professor Donna Noble

Luke Smith, the adopted son of Sarah Jane Smith and one of the protectors of Earth, looked up when he heard the classroom door slam open, he was half expecting to see the Doctor with that entrance, or his professor. What he saw was not what he was expecting. Instead of the Doctor or his professor, he saw a tall, lanky figure, wearing a worn black, leather jacket, and a even more weathered looking fedora and a long multi colored scarf. As the figure unwrapped the scarf and took off the fedora, it was revealed that the figure was woman with tanned skin, ginger hair and piercing green eyes. Her hair was cut short, just touching her ears. "Good morning, class," she said, "I`m Professor Donna Noble, and I will be your substitute teacher for the next few weeks." (cue classic Who theme).
