Sheri hitting the stop sign and not calling the police to report it or letting someone know it may have contributed to Jeff's accident is one of the reasons she killed herself, but Hannah was in the car, was the reason Sheri was distracted and she didn't tell anyone either.
I'm interested in how the second season plays out when more people hear the tapes, when the public becomes aware of the contents.
Jess' pops gonna lose his shyt when he finds out Hannah watched his daughter get raped and didn't tell anyone.
Jeff's parents are gonna be upset that they buried their son thinking he was driving drunk when Sherri and Hannah knew the truth.
