I agree, that was how I read it also. Plus Klaus telling Gil to beware of this greenhaired girl with two swords who is probably there to kill either Gil or both of them. Of course Zeetha knows nothing of this, having no idea, after barely surviving illness and pirates, of who Gil is, if indeed she ever knew that detail. She was meant to be on an exploratory and diplomatic expedition, I think? Zeetha and Gil seem to get on quite well just as people, and both seem fond of Agatha.
I wonder how much of this, if anything, Boris knows? Remember Boris, Klaus’s four-armed secretary? Skifander does seem to have both natural and synthetic four-armed people. I wonder if Boris was a natural four-armed child who was the son of somebody important enough that his being male was a problem, and whom Klaus rescued along with his own son, Boris being somewhat older than Gil at the time, maybe an early teenager?
