I finished the quest missing parts and decided to kill Vacor instead of Unzel.
But now I am trying to finish the old friends? quest. I met Kaverin in Remgard, went to Unzel but he is only thankful for helping with Vacor and that we are save now.
There is nothing else he says.

Does anyone knows anything on this? Did not find this situation in the forums.
Thank you for this great game and for the help.
