Since most companions aren't really the best of friends, why would they run around gossiping to eachother about something i said or did, and even if they did tell eachother, the offended companion should confront me and ask if it's true, or ask why i did what i did, maybe i would get a speech check to convince them it was the right decision during those circumstances or something like that, just getting an automatic disapproval from someone through hearsay isn't really fair.
