The Matriarch sex scene heavily implies that she does enjoy the sex, even if he did steal the artefact. I could see the two having a more peaceful relationship after defeat after defeat.
Also, I do think once you take all the artefacts, you should add some unique bad endings compared to having none or less than 3 artefacts.
Once you do gain all 3 artefacts from the Scar, is there going to be a non-confrontational relations with any of the characters, where you can interact with them like any other NPC with dialogues and each of them with their own bad ending caveat if foxxx is too tempted by the NPC in question? tldr all artifacts collected, oliver leaves, non-fight conversations with unique sex scenes and bad ends compared to the fights.
