Cerulean Cape Fundamental differing

It seemed no one knew how to help his brother; it was not surprising news. He considered bringing up the listener and her promise to help rid Alduin of his sickness, but then he would have to reveal that blackwater existed, which was against his rules regarding the druids. He did not give away information to anyone outside of the pack, not even to his own father. 

Though it was fine to mention the pack existed, he realized. He just wouldn't go into detail on the druids or their beliefs. As the speaker, it was his responsibility to keep that knowledge safe and out of the hands of those who had not been accepted as a druid. 

I thought maybe this mission would help, but he seems to get worse as time goes on. How long would it be before he was no longer Alduin anymore. What would he do then? He didn't want to think about the possibility of taking out his own brother. 

How is Atka? he asked, eager to change the subject.
