William is depicted as a unique and idiosyncratic young man with a collection of unusual behaviors and habits. Despite the challenges he faces in making friends and fitting in with his peers, he seeks to be accepted by others and be perceived as interesting and intriguing. His speech pattern is distinctive, with a snort at the end of each sentence, and he has an unusual appetite. He desperately wants to be seen as "normal" and cries about it alone everyday, and is very insecure about himself.
