While being given a tour, Julian makes rude comments that are supposed to call out Auggies special needs, treating Auggie like he is not as smart.

Then, we truly see his mean nature in the science lab: For instance, while Charlotte is talking about her acting career, Julian rudely asks the latter if she ever stops talking. Julian is also shown to be mean in general (which gets unnoticed, due to his 'king of the school' status). However, unlike the other two, who had grown accustomed to Auggie, Julian kept and grew his ableism of the latter. Like the other two children, Julian was a little bit unsure about meeting Auggie. Julian was first shown as one of the three students, who were tasked with giving Auggie a tour around Beecher prep, along with Jack Will and Charlotte Cody. Though it’s shown he has dark brown hair and brown eyes in White Bird: A Wonder Story. On the cover of The Julian Chapter, he appears to have dark, longish hair. He is no longer hateful and learns that he must spread kindness and love to all kinds of people, not just the ones who care for only him. On summer vacation, Julian reformed in to a nicer person after realizing that he was in fact an enemy to the school (mainly August and Jack).

Soon he grew jealous and left Beecher Prep with a broken heart. As the year passed on, he became bitter, hateful, and aggressive towards August, Jack, and later the rest of the school. When he met August, he became the least acceptable student to him. Julian started out to be sociable, energetic child who dreamt of fame and appreciation in a snobby tone.
