I've seen much discussion of the passage in which Horn says that because he [Horn] is on the whorl, then Pas is also there. I don't think it is that cryptic a passage. I think Horn routinely makes statements that confirm he knows
1. That Horn is dead and his body is rotting on green
2. That he is in Silk's body
He can talk about all the peripheral issues unemotionally and accept them, such as realizing that Silk and pieces of Pas have merged and are present in him. The only thing he cannot look dead on and accept is that Hyacynth is dead and Silk will have to live without her now.
So talking theoretically about Pas being present blah blah blah doesn't upset him, but accepting that he is Silk and Hyacynth is no more crushes him.
Just my two cents on the matter (smile).
And if I may be so bold on another subject. Alga I miss your voice/insights here, even though I know you didn't like Wolfe's treatment of Jahlee and women in general in this story.
