"Lochiel and I had almost come to a point where we were both over the things that happened, and could talk again like normal people - but since he fell in with Eris, he snarks at me and treats me with contempt and infallibly manages to make me look like an idiot to whoever might be there, Apropos or Esk or whoever. Well, Eris is the goddess of discord, so of course there would have to be some of that between her new follower and his former god."

Asar-Suti is really hurt by this state of things. If you're truly over somebody, you're supposed to get along with them civilly, aren't you? And Lochiel simply won't.
