Answer: b He talks in his sleep when she's close to him; Images from his new book
Step-by-step explanation:
In The Book Thief, Max Vandenburg is a Jew who is hiding out with the Hubermanns family. When Max reaches the Hubermanns' house, he sleeps for three days and in this time mentions names and shakes quite a bit sometimes even disagreeing with someone or thing in his sleep which scares Liesel.
Another way Max scares Liesel is when she looks in a book he is writing where he draws pictures of Hitler spewing propaganda and a picture of a couple standing over dead bodies under a swastika sun.
