親從何來 Where Would Kin Come From
沙僧笑道:「二哥胡纏,我們走了這些時,好人也不曾撞見一個,親從何來?」八戒道:「不是親,師父那裡與人哭麼?我和你去看來。」沙僧笑道:「二哥胡缠,我们走了这些时,好人也不曾撞见一个,亲从何来?」八戒道:「不是亲,师父那里与人哭么?我和你去看来。」

Sha Monk laughed and said, "Second brother, you are talking nonsense. We have travelled all this time and never once run into a decent person — where would relations come from?"
Sha Monk's joke is drier than anything Bajie manages. In all this walking they have not met one good person, so the odds against meeting a relative are poor.
Bajie said, "If they are not relations, how would our master be standing there crying with somebody?
Another question-word 那, read nǎ — "how would he be," not "over there." Chapter 80 splits its twelve uses of 那裡 eight to four between the question and the plain pointing word, and this is one of the eight.
You and I had better go and see."
Six characters, and the pair of them set off. Neither has thought to wonder why their master called for disciples rather than simply untying whatever it is himself.
The two of them argue about it like colleagues, which is exactly the register the scene needs before it turns. Neither has any idea what is waiting, and the book spends a passage on their banter while a demon sits tied to a tree a little way off.
Bajie's reasoning is sound, incidentally. His master is crying with a stranger, and the only explanation he can construct is kinship. Everyone in this chapter reasons correctly from the evidence they have, and only one of them has the evidence that matters.
