"Same answers, Class? Please don't forget to sign the Honor Pledge. Leave your bluebooks on my desk,"

Huh? This left-leaning moral absolutist is now utterly confused. You describe the situation as "changed just a bit." To me, the additions change the scenario entirely. Robin's giving his blessing to Marion means that no betrayal of a personal trust is involved, and Marion's refusal to comply with the Sheriff appears to be in harmony with her internal moral code, as opposed to the initial scenario, where she appeared to breach her own ethics. In this scenario, I would score Marion first for sticking to her own values, Robin lagging behind for asking her to compromise those values for his sake, and LJ neutral. "the lurid sexual scenes between MM and the High SR" had me confused, I thought she declined the Sheriff's proposal - are we talking about rape here?
