Ive talked to the leader of the graybeards (the dragon that keeps slipping into its own language) about the elder scroll and then i did the (optional) talk to greybeard (cant remmember his name) and he said talk to the (i cant rememmber his name either, but he's a dark elf and he keeps talking about the books in the collage) in winterhold collage, and when i made him tell me everything (when all the text is darker), it still has the quest marker over his head! He wont even tell me anything about it! What do i do?
