Coincidences
I agree with David Lebling that the coincidence of Jahlee being Krait's mother is a bit of a stretch.
I also find it a bit unsatisfying that Wolfe tends to revisit established locales. Was there any reason why the ship in Return had to be the Samru? I didn't notice any particular continuity in the character of the captain, nor any motivation for his later kind treatment of Severian.
In Urth of the New Sun, the boat that picks up Severian happens to be Eata's.
I also have a nit concerning Blood's mansion. Wasn't it off the Old Palustria Road in Long Sun? In Return, it's on the road from Viron that ends in Endroad. Perhaps the road doesn't go all the way to Palustria any more?
