The chapter starts out with Montag watching the pile of books that he lit on fire, burn.
The Sieve and The Sand
They were reading books and then Beatty walked in the house and they were scared that Beatty was going to burn the books and them.
Guy Montag and Mildred here scratching at the door and they get scared its a person because they have their books out. Then Mildred asks him why the door-voice doesnt tell them but he said it's because he turned it off and they went back to work.
Montag and Beatty were playing cards when the alarm voice in the ceiling chanted. Beatty told Montag to just put the cards upside down and they will come back and play.
They bomb the town and everyone seems pretty okay with it for some reason.
I think that after the explosion they can't Montag because he fled with all his new friends to a different country. Once he gets to his destination he is going to change his identity and everything about him so they won't recognize him.
