This has been something I have been brewing in my head for awhile now and I felt it was about time I put it out there. Basically speaking your companions follow you everywhere you go solo wise. They are there with you through most of this storyline you live through. I do not think this type of scenario is something in the game at the moment but alas I do not personally know. The scenario for each side is pretty much the same. Lets say that your companion is with you on a mission. At the end of it you either choose to kill someone who is a criminal or let them go. Lets say you make your choice and your about to carry it out. What would you do if your companion stops you and asks you to do the opposite? Please for the sake of this choice assume that it would not be a significant light side dark side point gain or loss. Would you then rethink the option and go ahead and do as you companion asks? Would you even give it a thought before denying it? Something I have been milling over and was curious to see other peoples responses, mine is below.
Personally my IA is going to be a healer. She is going to go full on darkside and do anything to advance herself and keep the Empire safe. If a choice presented itself where she wanted me to save someone I would probably kill them without hesitation anyway. I would be very curious to see where the story goes though. It may make a very interesting and involving plot.
