I don't know how open you are to suggestions, but it occurs to me in a modern AU the idea of keeping someone's memory alive and not letting the person who wronged them escape judgement vs. allowing their loved ones to process grief in peace might make an interesting metaphor for his ingame refusal to let Rachel die and conflict with her family.

Maybe he could be really big on not wanting anyone to forget that 'this is Rachel and a grave injustice was done to her' - yelling about it on social media, bothering local news outlets constantly even way after the fact, etc. - and in conflict with a family who just wants to be able to grieve (and who maybe process their grief in part by blaming him for 'dragging her into trouble', whether that's fair or not).
