Albert Martin included that anecdote to show that even an experienced fire chief was disturbed and affected about what he saw even though he was used to see fires. He took the mouse because it was the only survivor. He was happy that at least something got to survive. This anecdote about fire chief Crocker bringing home a mouse from the remains of the fire serves to remind the reader that even someone like Fire Chief Crocker who was incredibly experienced in fires and had seen many tragedies in his time was very disturbed and bothered by the Triangle Fire.
Explanation:
not much context on the question but I hope this helps and is right :)
Figurative speech is words which do not have a literal meaning but represent something else. The passage mentions that Bindi is a warrior. This doesn't mean that she is an actual warrior. It means she is strong and courageous as a warrior should be. She is also an individual with a growing talent who has an ability to perform very well. So while she is also a great performer, the figurative language is referring to her strong personality.
