In this part of the tape, Hannah seems to really want her listeners to take away a lesson from her story. Rather than coming away from it only knowing how they’re personally to blame, she wants them to reflect on how their actions could affect someone else really deeply, even though they might not have meant them to. The night Hannah calls “our night” is also a night that Clay remembers vividly, thanks to a separate, traumatic incident, which is a coincidence that seems to link him and Hannah together in ways he doesn’t yet understand.
