In the Smoldering Bar section of the hive there is a woman named Elyse who wants you to stop her boyfriend and brother from killing each other. It's most likely from the Unfinished Business mod. Is there a way to succeed in this 'quest'? High Cha maybe?

you've got to convince either the brother or the lover. i do it with 13 cha, so i dont think high cha is needed.
