公主道:「你認甚親?」老妖道:「認你父王。我是他駙馬,他是我丈人,怎麼不去認認?」公主道:「你去不得。』老妖道:「怎麼去不得?」公主道:「你认甚亲?」老妖道:「认你父王。我是他驸马,他是我丈人,怎么不去认认?」公主道:「你去不得。』老妖道:「怎么去不得?」
逐句解 Line by line
The princess said: "What kin would you claim?"
認親 again: to acknowledge, to claim kinship. 甚親 takes 甚 as shén, "what."
The old fiend said: "Your royal father, to be sure. I am his son-in-law and he my father-in-law — how should I not go and own the kinship?"
The comedy of this is in how correct he is. 駙馬 is the husband of a princess, an imperial son-in-law; 丈人 is one's wife's father. He lays out the whole grammar of in-law relations with perfect propriety, having acquired the relation by kidnapping.
The princess said: "You cannot go."
A blunt refusal. 去不得 takes 得 as dé, "cannot manage it, may not." (The closing bracket printed here is the irregular 』 of the woodblock edition, kept as it stands in the source.)
The old fiend said: "Why can I not go?"
He asks why, and gets the same 去不得 back, with 得 again as dé. The refusal is repeated before it is ever explained.
The exchange turns the imposture into a small comedy of manners. He proposes to claim kinship at court, invoking the bonds of 駙馬 and 丈人 with impeccable decorum — the same courtly reasonableness that has been masking his monstrousness since the chapter began.
Her flat "you cannot go" is what produces the transformation to come. As the next passage makes plain, her objection is not moral in the least. It is his face, not his intentions, that would give him away.
