So my top suspicions
at the moment (not reflected through, but now), at the order of suspicion, and at relative distance away from each other...
Naria / Roa
Caranlodien
Grendelien
Relatively assured of innocence:
Celuien
Zali
So the highest is the most suspicious, the lowest the least, regarding the whole list... But really: I don't know about these relative merits, this is just a hunch based on reasoning (=everyone's playing well)
PS. Remember: I may be somewhat skilled in bringing forward points or theories, but my hunches are bad indeed (in four WW-games this far, I have been proven right twice - or three times: and you just wonder the number of cases from which these three must be deducted...
