I have trapped Odahviing in Dragonsreach. He tells me that I need to get to Skuldafn, which is only accessible by air. He wants me to release him so he can fly me there.
This seems like it would be a rather bone-headed move, as this dragon is a devout follower of Alduin and it will probably backfire on me. It is even apparent in the written dialogue that my player character does not trust him.
Meanwhile, the Blades want me to kill Paarthanax, because they don't trust him. I'm not going to, because I do trust him.
So the obvious first thing to pop into my head here is that I should just visit Paarthanax and ask him if he can fly me to Skuldafn instead. Paarthanax has been helping me this whole time and even helped fight Alduin. I see no reason at all why he would refuse.
But I can't even talk to him about it. There is no dialogue or story tree to allow for this option. I can't be the only one thinking that this is the most obvious direction to take the story. What's the deal?
