YMMV / Not Simple

• Diagnosed by the Audience: It's not explained but multiple characters seem to notice Ian is mentally off. this can be seen in his single-minded obsession with seeing Kylie again, even after he becomes an adult, his moments of absent-mindedness and the fact he had no qualms about being molested.
• Fridge Horror: The rich woman that met Ian and took him out to dinner was his stepmother— the woman his father married after getting divorced. Meaning, Irene is actually Ian's half-sister, and Ian's father is the one who had him killed.
• Iron Woobie: Ian. Definitely, considering he only complains once throughout the Trauma Conga Line that is his life.
