Khaat, a newly hired substitute teacher had a personal motive for going to the fourth floor, and right now, the library had nothing to do with it. Khaat desperately wanted to find the Mirror of Erised. She felt the ache down deep in her heart for her beloved Uncle Remus--the grief that had never gone away when he was killed. If she could just find the mirror--see him again--maybe the terrible anguish she carried and tried so hard to hide would ease even if just a bit.
As she walked the hallways, looking in some of the empty classrooms, she felt her drive inside her rise. She felt like she just had to find that mirror. She opened one of the last doors and saw the mirror, covered with a canvas tarp. She went over slowly, reverently, and took the cover off. Staring into the mirrror, she saw Remus--and herself. He was excited about seeing her, and he hugged her closely, just as he had done when she was a child.
Khaat sat on the floor, unable to do anything else, but sit and stare at the images in front of her, feeling a confusing mix of joy and anguish at seeing him again.
