No, my question is: why wasn't Achamian's immediate reaction "let's go look at Kellhus with the Judging Eye like right fucking now then" instead of the slog to ishual. It just really, really stands out
He is ever the sorcerer and the skeptic. He feels one woman (the bitter, betrayed daughter of the Empress, no less) saying, "I have the eye of God, your savior is a fraud!" would carry less weight than some objective proof gleaned from Ishual. "Boom, whale-mothers, Proyas. Fuck this guy." Also, the very real possibility Kellhus sees him and hits him with the metagnostic middle finger.
Though I could just be rationalizing after the fact in defense of the series or authorial oversight.
