The fiend turned his head sharply, threw Sha Monk a glance, and said: "Master, I've been frightened out of my wits by that fierce tiger — and the sight of this ill-omened, dark-faced monk alarms me all the more. I dare not have him carry me."

抹了他一眼 (mǒ le tā yì yǎn) is a quick sideways look, a glance wiped across someone. 諕怕 (xià pà) uses the borrowed 諕 for 嚇 again. 晦氣色臉 (huì qì sè liǎn) is "a face the color of bad luck" -- Sha Monk's dark, grim looks, which the demon now finds conveniently terrifying.

Tripitaka called: "Wukong, you carry him."

The master, obliging a frightened old man, reassigns the burden -- and hands the demon the one carrier he was angling for all along. Every kindness in this scene lands exactly where the fiend aimed it.

Pilgrim answered at once, again and again: "I'll carry him, I'll carry him."

連聲答應 (lián shēng dá yìng), "agreed with one cry after another" -- 應 read yìng, "to answer," which is also the reading that will matter enormously once the treasure-gourds start calling people by name. Pilgrim's eagerness is not innocence. He saw through the costume some time ago.

The monster thereupon settled on Pilgrim, meekly consenting to be carried by him, and said no more.

認定 (rèn dìng), "to fix on, to settle upon." 順順的 (shùn shùn de), "all meekness, perfectly biddable" -- the sudden docility of someone who has got what he came for.

Sha Monk laughed: "This purblind old Daoist! Better I should carry him — instead he wants that one. Let him once lose sight of the Master, and on some three-pointed rock he'll have every sinew in your body smashed to bits."

沒眼色 (méi yǎn sè) is "no eye for people," a failure to read a room. 顛倒 (diān dǎo) here means "the wrong way round, perversely," 倒 read dǎo. 摜斷 (guàn duàn) is to dash something down and snap it, and 觔 is the edition's form of 筋, sinew. Sha Monk's parting joke turns out to be an accurate forecast.
