Augustine Baker: Even if Dr. Krah were merely a puppet of Bishop Fellay's designs, I think it will be much easier to attack Krah instead of attacking His Lordship, since Krah has no aura of ecclesiastical authenticity surrounding him which we need fear damaging.
AB: I find it hard to believe that the Society is entirely happy with Krah's litigious, and strikingly self-interested, behavior.
I doubt seriously that Kr. is a "puppet" of +F's designs. It may well be the other way around. "(A)ttacking" His Lordship is really no one's end game, in my opinion. Getting at the truth is. And the only way the truth will come out is when Menzingen clearly explains and defines Kr.'s role in the Society. They have not done that to date. If the Society is not "entirely happy" with Kr.'s behavior, we can not, with any authority whatsoever, say that they're not entirely happy. We have to at least entertain the notion, in the midst of stoney silence, that they might be "entirely happy" with him.
For those who aren't familiar with the reference. Grima Wormtongue was a diminutive and cunning servant of King Theoden, a parasitical and evil counselor of the King whose agenda was to serve the interests of Saruman and ultimately his own, as I think he wished to rule Rohan himself when the King had been disposed of. He kept the King from his family and his most trusted servants and encouraged a policy of non-engagement against the encroachments of Saruman's armies in Rohan.
Those of nobles of the Rohirrim called Marks, who "disobeyed" the King's orders by resisting Saruman were branded as outlaws, and it wasn't till Gandalf arrived to break Wormtongue's demonic hold over Theoden in a kind of exorcism, that the King became free to defend the true interests of Rohan and the free peoples of the West.
It might seem a little dramatic or even loony to use such an illustration, but it's what I'm going for when I think of what Krah is doing to the Society and the amount of division he's causing.
