The Lion, the Witch, and the Wardrobe starts out introducing the characters, and the action starts happening right away. Although their introduction is short, the characters are well developed and easy to relate to. Each have unique qualities that help them through their adventure. When Lucy passes through and meets Mr. Tumnus we qiuckly have an idea of what kind of Faun he is. After he brings her to his cottage we see that he is a scholarly type, having several books concerning mythology, science, and history. Since as we know that this book has Christian undertones, this may be a reference to the dying out of paganism and a turn to Christianity.
Mr. Tumnus proceeds to entice Lucy to stay in hopes of kidnapping her, but the fact that he does not turn her in shows that he was good, but felt that he had no choice. This also implies that he will play an important role later on in the book. When she returns, no one believes what she has told them about the wardrobe. This is where the professsor comes in and plays the role of the gatekeeper. He tells them that logically, Lucy is not lying, nor is she crazy. To their shock, he encourages them to go and explore Narnia. This probably helps them when the time comes to accept the challenges set before them, since of course, if an adult says it is true; it must be. Evidence suggests to the reader that he knew Lucy was not lying he himself had been.
When Edmund joins over to the Queen's side, it is evident that his concience tells him that he is wrong. He soon regrets leaving his siblings and his anger turns to shame.
