Pilgrim said, "Right, right.
He gives way at once, which is unusual, and it is the abbot's argument about the master that does it.
Let me take the cool water to my master to drink, and then come back."
The errand he set out on twenty passages ago, finally remembered.
He caught up the alms bowl, poured cool water into it, turned out of the fragrant kitchen, went straight to the abbot's quarters and called, "Master, drink some cool water."
著 is zhuó here — the applying band, to put a thing on or into something — distinct from the sustained zhe that this character takes elsewhere in the chapter and from the dispatching zhuó of sending a monk on an errand.
Pilgrim yields to the abbot instantly, having refused to yield to anyone else all chapter. The argument that works on him is the one about his master's safety.
The bowl of water has now been in his hands through the discovery of six murders, a long recitation of monastic life, a boast about heaven and a proverb about battle. He carries it back and it is still cool.
There is a small structural pleasure in the return. The chapter sent him out for water at the end of one scene and brings him back with it at the start of another, and everything in between has changed what he knows.
