So I'm on my second playthrough, and this time I'm making alternate decisions from my first run. So I get to the Dalish Elves...last time I sided with them so this time I figured I'd side with the werewolves. 

Not a big fan of reloading an old save, but that will probably do it, since I want her in my party endgame.

I'd say reloading an old save and going the other way is more 'cheating the system' than anything else in your post.

Eh...true. Buts its my second playthrough. Went only forward first time. I was more refering to party members being aware/unaware of actions based on party presence 

After I did some pretty reprehensible things in the Sacred Ashes quest, I lied my ass off to keep Leliana around. But I guess you can't wheedle your way out of every bad situation...

I hadn't encountered anything where someone outside of the immediate party took an issue with my actions.  Very interesting! 
 

Why would anyone turn down Morrigan . . . . . 
And if your plan succeeded, that wouldn't be cheating the system, it would be the system bein retarded.
