逐句解 Line by line
The white horse, knowing him for Bajie, suddenly uttered human speech and cried: "Brother!"
The horse talks, and that is a genuine event. 認得, to recognise, takes 得 as de; 口吐人言 is literally "the mouth spits forth human words." 那 is pointing nà. Across the journey this animal is essentially silent; he carries Tripitaka chapter after chapter and says almost nothing. Tonight he speaks.
The blockhead started so he fell in a heap, scrambled up, and made to bolt outside.
嚇了一跌 is to be startled clean over, and 扒起來 to scramble back up. Even at the moment of wonder, Bajie falls down.
But the white horse stretched forward and with one bite caught his black robe: "Brother, do not be afraid of me."
皂衣 is a black robe; 探探身 is craning the body forward. The horse has to physically take hold of him with its teeth to stop him running away, which tells you everything about the state of the rescue party.
Trembling, Bajie said: "Little brother, how is it you've begun to talk today? If you speak, there must be some great calamity afoot."
戰兢兢, trembling and shaking. Note that Bajie's instinct is entirely sound even while his nerve fails: a horse that starts talking can only mean catastrophe.
The breaking of silence is a marked moment. Through nearly the whole journey the dragon-prince serves mutely as Tripitaka's mount; here, forced by the crisis, he speaks for the first time, and the bare fact of his speech carries the weight of the emergency. Bajie's terror registers how unnatural, and how serious, it is.
Comedy and urgency are finely balanced. Bajie tumbles over and bolts; the horse has to catch his robe in its teeth to hold him; and Bajie's frightened guess — that a speaking horse means "some great calamity" — is exactly right. Vernacular fiction routinely lets its clown blunder into the truth.
