From the blog "Lianeline's fantasies"
(...)
"If I become a companion, will you tell me about my brother?"
"No I won't, and I doubt that the others of the circle will either. Part of it is to keep our shame hidden, but believe me when I say that if you knew, you'd wish you didn't."
"Will you forbid Athis to tell me what he knows?"
"No, but I doubt that he knows much. Still they were close for a while, him and your brother, so I may be wrong. But your dealings with him, and what he makes you do are between you two.
