So, I made Vilkas to go-to guy for one of the houses I'm making with the Hearthfire DLC. I also just took him on his Purity quest. Problem is, I don't get a speech option to ask him if he's okay and yadda yadda to finish the quest, so now I'm stuck with him following behind me, with only the house related speech options, and no other way to finish the quest. I tried reloading a save (not to one before I made him my houses go to guy, because then I would lose a ton of progress) and I tried beating him until he turned on me, then talking to him again once he stopped trying to kill me. Any ideas?
