He has not spoken to myself or Bryn in weeks, and his complete disregard for Bonnie being replaced, as well as his lack of caring for what happened to Erandur. He should be the one of ones yelling the loudest for a call to arms. These facts lead me to believe he has been replaced.
Then, there is this. I have to ask, in as long as you two have been together, when has he ever not wanted to touch you?
Ask him how the two of you met or something equally as personal.
