Well that appears not to be the case. Perhaps ANS did not talk to her physician pal, close confidant Eroshevich about her actions or feelings. But ANS talked to the world, to Larry Birkhead, and according to HKS, sure did talk to him.
"her physician pal, close confidant Eroshevich"
That description is ALWAYS used. Apparently, ANS talked to everyone BUT KE.
