Peer groups include individuals of the same age and related social position (Willmott, 2018). This is noticeable in Thirteen Reasons Why with Bryce. Additionally, when Bryce is with his peer group, he seems to be a friendly and outgoing person. However, when he is alone with girls, he sexually assaults them. He sexually assaulted Jessica while she was passed out and had non-consensual sex with Hannah while he was alone with her in the pool at a party. Hannah was already suffering so much psychological pain and Bryce was the penultimate horrible event in Hannah's life before she committed suicide. Hannah even mentioned that Bryce's actions were a big reason why she ended her life. In this case, Bryce being with his peer group is an advantage, because when he is with his peer group, he is not taking advantage of women. Flashing back to when Hannah and Marcus went on their first date, they went on a date together and Marcus' friends were watching the date. Before the date, Marcus had acted very respectful and sincere as they only spoke alone. When they go on a date with Marcus's friends, he attempts to sleep with her. The addition of Marcus' friends to this date revealed the type of person he is when he is with his peer group. The addition of Marcus' peers to the date was a huge negative and hurt Hannah's feelings when she realized he was trying to impress her friends. The article entitled "Peer Groups as a Context for School Misconduct" discusses a test applied in all schools regarding the positive and negative effects of peer groups (Boyko, Chen, Ellis, Kinal, Zarbatany 2017, 1). They found that negative peer group actions become more widespread (Boyko, Chen, Ellis, Kinal, Zarbatany 2017, 2). The study also showed that members of a peer group were more likely to remain members of that group if it was a group with a positive orientation, but that people were more likely to.
