Chloe says, "Apparently, Julian's genetic background has a lot to do with it. His father and grandfather both had very similar repetitive routines and high anxiety about contamination."
Marcus says, "That is interesting. I read that OCD is actually linked to imbalances in chemical messengers and atypical activity in certain brain pathways."
