After completing the Companions quest line, I went on to do the side missions afterwards. I started with Farkas on the quest Dragon Seekers.
Our target was the dragon at Bonestrewn Crest. I fast traveled to the location because I had been there already and killed the dragon before. When we got there the dragon was hovering about and Farkas and I easily killed it. However, the marker lead about a hundred yards from the Word Wall and killed the dragon did not satisfy the quest.
I wouldn't mind ditching this quest if Farkas would stop following. I've tried many things. - Waiting weeks and killing the other dragons that spawn. - Killing Farkas. - Marring Farkas. (Gay) - Getting others to kill Farkas.
My last save was after I killed the dragon too. Also I am on the Xbox. Thanks for the help.
