Peter

When Father Christmas handed him a sword and a shield, Peter was at least as surprised as his sisters, but he walked forward and took them. To his shock, they did not feel wrong in his hands. It was as though they were being returned, rather than given. When he made to draw the sword, Peter slid the shield on his arm to free his hand without thinking. After they bid Father Christmas farewell, Mr. Beaver made to help him with the sword-belt and scabbard, but again, Peter was surprised to find that he could see quite easily how it worked. As they walked through the snow, he puzzled over his sudden and strange understanding of weapons.

Maybe not so sudden, the part of his mind that already believed the prophecy interjected. I've always loved the stories of King Arthur, and when Ed and I were little we used to play at sword-fighting with sticks… His gut clenched when he thought of his brother. How am I going to help Ed? Can I really fight a war to get my brother back?

Don't be ridiculous, the skeptical part of his mind said, you're a kid! You know don't know anything about swords and shields and wars.

And as he panicked on the frozen river, reaching for the sword he'd recently been given to try his best to defend his sister and new friends against the White Witch's wolves, Peter was in a quandary. Susan yelled for him to be sensible, but what was even remotely sensible about this situation? The Beaver yelled for him to kill the wolf while he had the chance, but the river made this decision for him. Lucy shrieked and, as ever, Peter's attention was drawn to her distress. His instantaneous decision to use the sword as an anchor was proof enough for his troubled mind when he thought about those heated moments later. This weapon was not only destructive; he had used to save his sisters and himself.

If that was what a sword was for—to protect the people he loved—then maybe he Could be the warrior the Narnians expected him to be.

Note: I chose to change the point of view of Peter's thoughts because I wanted to associate the optimistic side of his personality with his concept of "I," while the more skeptical part was his mind's rational assessment of his hopefulness.
