The third monster said, "That little fiend who reported just now is no Little Bore-Wind. He is Sun Wukong himself.
Flatly stated, with no hedging. Compare the way the chief handled the giant, which took him three clauses and an inference. The roc simply names it.
He must have run into Little Bore-Wind, and somehow beaten him to death — who knows how — and then transformed himself to come and fool us."
He is entirely right, including the detail. Wukong met the scout on the road in the previous chapter, questioned him, ground his head to pulp with the iron cudgel, took his badge and bell, and put on his face. The roc has reconstructed all of it from a snicker.
Wukong panicked. "He's recognised me."
認得 keeps 得 at the full dé — the verb to know a face, not the light de. Eleven of its twelve sealed sites read dé. What decides it is where a 不 would sit: 不認得, plain does-not-recognise, keeps the full dé, while 認不得, cannot-manage-to-place-him, takes the light de. And note that this is the second time in four hundred characters that Wukong has been frightened rather than pretending to be — he took fright in his own heart when the doors first shut.
The reconstruction is the point. The roc does not merely suspect; he works out the whole sequence from one wrong sound, and he gets every step of it right. This is a novel that generally lets its monsters be fooled, and it has just put one on the board who is not going to be.
Wukong's reaction is three characters and no plan. The gap between that and the elaborate improvising of the last six passages is the whole measure of how much trouble he is in.
