Allison

The Basket Case

During detention, Allison shows disgusting personal habits, causing everyone to stare at her in shock - especially during lunchtime, when she puts together a sandwich with sugar candy sticks and Cap'n Crunch Cereal. She doesn't really start talking until after lunch, and at one point, she even dumps her bag full of junk on the couch.

Physical appearance

Despite some insecurities, Allison is a beautiful teenage girl with a slim figure and average height. Her hair is dark brown with an occasionally black hue sometimes, and it tends to cover her face and appears to be shoulder length and wavy. Her skin is pale with very light freckles, and her face is often sorrowful and has dark brown eyes with black eyeliner, a button nose and small pink lips.
