Andor's Trail

At the final conversation with Buceth I promised him that I’d keep everything in secret, but I lied, because I didn’t intend to bring Andor in grief, if it had been really him at the well that night! But I didn’t think that the quest would be closed by doing so! If I had only suspected that Buceth had an antidote, I would have definitely got it! (I read about it here on this site.) I tried to return to Kuldan to report him even so, all in vain of course.
Now I am disappointed, because I wanted to help the village so much, and I regret that there’s no way to change my mind (as I made my choice not being aware of the possibility).
I guess you don’t intend to change this part of the game (e.g. to build in a possibility, that returning to Buceth again we could choose to tell him that contrary to our promise earlier, we will tell everything to the guards). I also know that logically this would interfere with the fact that the quest is in completed status at this point.
I also would be pleased to get the chance to aquire an antidote from Lodar, when it is possible to find his hideaway (as I understood, it is not in the game yet).
