Pretty much, although Herbert's mainly stuck on the "her hair is terrible" thing right now :D

Alas, that his relationship with her is something he wouldn't discuss, save under the most horrific of tortures. He still feels hurt by the way she used him, but he knew it would never be a normal relationship and they did get their resolution at the end of S7, so I think it'll be his secret for a good while yet.

Give it time, though, and it'll eventually come out, I have no doubt.
