I guess I have to give up. I've spent a lot of time in Markarth doing things for the Jarl and the people and still he keeps saying to be good to his people and he'll be good to me but doesn't make me Thane so I can have Argis the Bulwark as a Housecarl/Follower. From the wiki, it says to do things for the Jarl and 5 things for the people of Markarth. I've done more and still nothing. I did 2 or 3 Bounty letters for the Jarl too and recovered the family shield for him and own Vlindrel Hall. Does anyone know what I need to do to trigger the Thaneship dialogue? This is the second game this has happened...I must be missing something. Thanks for any help.
