The Lion, the Witch, and the Wardrobe - Chapter 3 - Edmund and the Wardrobe

Lucy's siblings don't believe her when she returns especially because it would appear absolutely no time has passed.  They tease her but the next rainy day, Lucy goes into the wardrobe first and then Edmund follows her but doesn't find her.  Instead he meets a Queen in a sleigh, which we know has to be the wicked White witch.
