Cassandra gave Ren a smile, "You're a shocking liar Ren" She said, "I slept about as well as I have for the last few months, so crappily" She said, as she bit into her apple, chewing thoughtfully, "I think you worry too much about your looks. Have you seen an exorcist without a scar?" She asked rhetorically, "Even Oliva has one, that can be seen. On her arm, just here" She said, pointing to halfway up her own arm "As for my hand, I got burned badly as a kid" She decided to just go with the same lie she had with Kiddo, "Glove protects my skin" 

She finished her apple, and made a note in her homework, leaning back, satisfied with it, she nodded. and packed it away, taking a drink of water, she pushed her finished food dishes away, and checked on her sword, "I use to go about without the glove on, but that proved too painful, and its kind of scarred, so I started to wear a glove. Most people think I'm mental, wearing on glove, but it works" She shrugged.
