Weirdly, I read Kellhus' forthrightness with Akka to be as warm & cuddly as he gets. At least there's no manipulation, I read it as saying 'you can't do anything for Proyas, concentrate on the lives you can save'. Plus, some shade, but that's normal. IMHO, Akka's women are going to have a lot to do in coming weeks and month, so this could be Kell dropping some hints for the next series.
