Exactly. If you're love interest is a cleric and his God asks him to stop seeing you than either you're doing something 'evil' to irritate the god or the cleric is following a darker, more ambiguous (possibly 'evil') god and that kinda disqualifies him from being a KISA.
Edit: This is assuming of course that the god is annoyed by your actions. If it's sending the cleric to the other side of the world to save orphans or something than that's still equally applicable to a religiously unaffiliated KISA.
He could be a KISA and not realize that his god is evil. That would make for a great story. Swinging this back to DA, we've talked about an Avvar as an idea before for a KISA. What if he/she thinks that they spirit they follow is benign, and just an average nature spirit, and it instead turns out to be a very subtle and clever demon. He now has a conflict between his "god" and his own Code.
Personally, that's the kind of internal conflict I'd like to see. The writers touched on it with Cullen, but he's not only straight, he's monotheistic. I'd like to see the perspective of a polytheistic group, and in the spirit of the thread, one that isn't heterosexual.
I love the idea of a demon posing as a very good spirit. Quietly manipulating the KISA until the player as well as direct evidence is presented to companion. Then they have to make a choice. I could picture it now: Someone posing as good and helpful, maybe even in a physical body as an adviser or dear friend, only to be subtly controlling the character all along. Like in the first Bioshock, with the arc words "Would you kindly...."
Don't mind me, I'm just spitballing some random ideas that have been rattling around the back of my brain.
Still doing the Kaidan romance, and I'm a little over 1/2 way through ME2 with Natashina Shepard. I did tear up slightly at the reunion at Horizon, mainly because he sounded so incredibly frustrated. However, I'm a good kid and remaining loyal until ME3. I did the romance in the first game and it was totally worth it. I never disliked Kaidan, I just never really used him much. He's grown on me a lot. Plus, in either ME1 or ME3, put him and Liara in a party together to destroy everything in your path with biotics. Liara plus Kaidan plus Infiltrator Shep = Undead Saren dead again in less than 90 seconds. Anyway, Kaidan's romance actually shows a little more of his KISA side that I've noticed.
<hugs to her favorite DA thread> At this point, I'm waiting for patch 7 to come out and then I'll be picking up the DLC and get back into DA.
