Voice of Reason?

Kenner speaks as Creighton in so far as he is written to say what the author thinks. Yet, is there too much dialogue in how this is done? I would say that, while it tends to be useful and relevant dialogue, that yes, there is a lack of action on Kenner's part. He seems to be more of a vault of random information that has been given a name, than a true character. He pushes the story along as an enlightening figure, revealing information as it is deemed necessary, instead of letting the other characters discover it. And when Kenner goes on tangent about the usage of item a, or the effects of item b, it only further points to his being a dictionary on legs rather than a believable person.
