Explanation:
1) "'lady, i am sorry' whisper the boy"
2) "dragging the frightened boy behind her"
These both show how the boy is scared. in the first examples, the boy whispers which show that he could be trembling. the second example, (which isn't a good example) show that he is scared of the woman. the woman seems to want the boy to be scared and she doesn't have any respect for the poor boy, this is also shown in the line "she did not release him".
