Five Hundred Years After/Issola spoilers. 5HYA: Many Jhereg believe that Mario is "...always searching for the one woman he ever loved." This would be consistant with Mario's personality, and the "searching" part implies (admitadly tenuously) Pathfinder. At the end of _Issola_, Sethra refers to GWs "waking up" which may be able to explain some of Brust's comments concerning events immediatly prior to a scene (forget which book) in which Vlad talks to and is almost killed by Aliera. 5HYA: "...Many believe that [Mario], body and soul, arrived in the same place as Aliera's soul..." While the word "body" may weaken my argument, Issola shows how that "place" may be Pathfinder. Compare Vlad's metaphysical experiences. All right. There might be more, but I guess "all sorts of evidence" was something of an overstatement. I won't pretend to have anything concrete, but IMHO it's an interesting idea.
