so the almost next to useless blades told me to kill my buddy Master P. nope. I figured I would go talk to him about it, but dialogue was limited. Then I went to greybeards and the Dialouge choice allowed me to promise I would not kill my good buddy Paarthurnax. but the quest is still there. It should fail. You should be able to say "no!" and have the quest just fail. FAIL. like the washed up sorry ass blades.

you can just ignore it?

Keep playing the MQ and stop assuming the quest stays there.

I never got the quest until I after the MQ. I had always been relying on Paarth and the greybeards, was unimpresed by blades. when I went back to blades, I had a gltiched "give me dragon bones" thing but nothing else.

I killed alduin, thought I would be polite and go tell the blades. then they give me quest. I WILL ignore it.

in possibly related news, I found out esbern is essential
