Jessica's certainly one of the most sympathetic characters on the show. I could argue that Hannah let Jessica down more than Jessica let Hannah down. Cheating on Alex with Justin, of all people, is a little harder to defend.
How so? I'm not one of the trolls trying to start an argument I'm just curious as to why you think so. Hannah let Jessica down only one time and that was at her party, but all the other times Hannah was very kind to Jessica she even gave Jessica a ride home from the winter dance because she was drunk and that was after Jessica slapped her and ended their friendship. There were plenty of times when Jessica wasn't very nice to her and she did warn Jessica about Justin at her party before she got raped by Bryce and she also tried to tell Jessica what happened to her at her party but Jessica shut her down (we saw that flashback in season 2ep3).
I agree Jessica definitely let Hannah down in so many ways Jessica was so rude and selfish towards Hannah and only cared about guys instead of her friendship with Hannah
