Malrubius ghost

Looking over the Gevers interview (Magus of many suns) earlier and intrigued by one of Wolfes comments. He is asked "Does Silk/Horn take an active part via astral projection in the events of BotNS? Specifically as the "ghost" of Malrubius?" Wolfe replies "Yes but not a leading part." What does everyone make of this? Does anyone think that Silk/Horn makes appearances in the New Sun books? What about Malrubius being an Aquastor? Is that still valid?

Mmmmmm. To me, an answer like that suggests GW knows very well what lies deep inside the layers of the story that are inaccessible to us. I think his reply to Marc is to be taken seriously, as is the answer about Blue+Green. And possible the interview where he says something in apparent contradiction to 5HC.

Just taking a quick look through New Sun, I'd say pg. 77 of Shadow and Claw is the only plausible one, unless Severian is mistaken or the Rajan lying to him on the other occasions. Now, if he was ignoring the last part of the question, more possibilities open up.
