Ok I've hooked up with the Blades chick and went to the thalmor embassy and got the info. I met back up with her and got my stuff and she wants me to go to Rifton and meet some vendor there that might know were to look for the other old Blades guy. I go to Rifton talk to the guy I'm looking for but evidently I talked to him earlier in the game and took a quest from him to steal something from another vendors strong box. Then plant it on another guy so he will get put in jail. Well I'm not sure I want to do that to the poor guy now. But there is no other options in the conversation with him. Nothing about the main quest and finding the blade guy.
So am I glitched , do I need to do his quest 1st even though I don't want to, or do I need to follow him home and talk in private or something ?
Also without spoilers what percent am I into the main quest between 1 and 100.
