A few chapters ago Greg felt, suddenly and unexpectedly in the narrative context, "hopeful". This chapter has prompted me to realize that, with the singular and horrific exception of Nate's father, all your characters, including even such a minor one as Keigan's mother, are intelligent. The fact, then, that none of them can credibly run amok, gives me hope. An additional piece of comforting evidence, to me, Is a piece of Greg's inner voice while he is talking with Keigan: "Goodness gracious, was that peevish noise my voice? Egads!". Any character who can step away from himself and hear himself with such ironically bemused judgment reassures his reader.
