Tobias and his biological mother have both been diagnosed with schizophrenia. Tobias experiences vivid visual hallucinations, frequently seeing shadowy figures moving in the corners of his room. He also suffers from persecutory delusions, believing that a local secret society is monitoring his thoughts and plans to poison his food. Tobias also exhibits severe avolition, showing a complete lack of motivation to maintain personal hygiene and spending successive days sitting in silence without initiating any activity.
Tobias's psychiatrist believes that his symptoms are caused by dysregulated synaptic transmission in the brain and has prescribed a course of atypical antipsychotic medication.
