He is, and Ferbin is properly dead - the only place that could have taken a backup exploded - but I was only referring to Holse in the brackets. You can see during his trip with the prince that he's making an effort to understand and comprehend all the stuff that's going on, to the point where Xide Hyrlis asks Holse to join him, and I'm suggesting that Holse was also an agent, a newly recruited and trained one during the year he was away, and that the avatoid is his partner and watchdog.
That help?
