- In the world of Snowflake, Olaf is a young boy and fellow patient at the Institute. Olaf has two conditions: Autism Spectrum Disorder and a deathly allergy of sunlight (Of course, that may be the Institute's fault). His favorite season is summer, and he cannot go outside without getting burned. To make things worse, he was effectively abandoned at the Institute by his parents.
