I definitely knew Courntey and Marcus types in high school. The over achiever, super involved gunner types who were focused about their reputation and future and such they had no empathy for others. And yeah your right those are the people they don’t usually tell you to be careful of.
Yeah the end of episode 9 shows Jessica definitely had memories of what happened. I think she was in deep denial and wasn't exactly sure if her memories were real. She seemed to really depend on Justin and since he kept on insisting it was a lie she wanted to believe that it was but you could see it was having an effect on her, such as the heavy drinking. I honestly felt bad for her because not only was she raped but she was betrayed by someone she really trusted.
I'm just glad she told her dad at the end, meaning he'll most likely do something about it.
