Allen is a little boy with amnesia. His father (age 34) and mother (age 32) were murdered by someone, and he was outside when the incident occured. He claimed that he was too shocked upon hearing the incident, making him lose his memories. It is assumed that the killer is the Cheshire Cat. Then, he was found by the Teacher, and is the last (fifth, sixth if Rick is included) child that is found by the Teacher. He now lives with the other children and the Teacher in the unnamed facility.
