When something happens that is completely opposite the audience expects.
Based on the excerpt from Joseph Conrad's "The Lagoon", I think that it takes Arsat all night to tell his story. I have inferred such due to the sentence: "<span>Before his face the sun showed its edge above the tree-tops, rising steadily." This means that the sun has already risen. Arsat told a story about his past wherein he and Diamelen, escaped from the rajah's men. </span>
An infinitive is the word "to" plus a verb so if you see that in a sentence its probably an.infinitive (I'll give an example below)
Ex: Renee suprised her sister to scare her.
-The infinitive would be "to scare" because it could be mistaken as a verb but the actual verb is "surprised"
Hope that helped!
