When Hannah first moved, Jessica Davis and her were great friends but somehow ends up being Hannah's third reason for committing suicide.They were both new and a teacher had set them up together. Hannah and her new friend would meet up at Monet's after school and eventually became friends with Alex Standall. Jessica and Alex dated for a while but then they all slowly drifted apart and after Alex Standall had put Jessica Davis and Hannah Baker up against each other on the "Hot or Not" list, Jessica had heard rumors about Hannah "stealing her man".
These rumors were obviously false, but still put Hannah in a bad situation. Hannah and Jessica met up at Monet's to talk about the rumors, to clear things up. At the end of their conversation Jessica was jealous and furious,she hit Hannah on the face. Jessica left a small scar above Hannah's eyebrow, leaving a reminder. Another friendship destroyed over a stupid rumor, Hannah was fed up. Hannah said in her tapes that, it was more than just a little scratch. It was a punch in the stomach and smack in the face. It was a knife in the back because Jessica would rather believe some made-up rumor than what she knew to be true.
Jessica's story doesn't end here though. She comes up in another "reason" which was a second tape dedicated to Justin Foley. Jessica wasn't exactly named in this tape, but the people involved and Clay could identify Jessica. Justin Foley was enough to be Hannah's first and tenth reason for ending her life. On the night of the party Jessica was extremely drunk. Knowing this Justin allowed his friend, Bryce Walker to pretty much rape Jessica. Hannah was hiding in the closet during this time, but she couldn't help, she was too numb. She wasn't even capable of saving herself how could she have helped Jessica? Over the loud pounding music Hannah was in a closet, slowly letting her life fall apart. After Bryce had "spent a few minutes with Jessica", Hannah ran out of the room and got a ride with, Jenny Kurtz.
Jenny was number eleven on Hannah's list. Sure, Jenny was polite enough to offer Hannah a ride home, but on the way she hit a stop sign. The stop sign got knocked over which made it easy for someone to get hurt. After Jenny had crashed into the stop sign, Hannah tried to convince her to call the police. Jenny kicked Hannah out of her car and left her on the road. Jenny Kurtz didn't want to call the police because she might have gotten in trouble. Later that night, there was a car accident due to Jenny's crash and a senior from their school had died because of it. Hannah could have helped out two people that night by stopping Bryce and calling the police. But now, she was broken and her life was just getting worse.
