The most important line from part 1 is when Captain Beatty says, "We don't get overanxious or mad. We let the fireman keep the book twenty-four hours. If he hasn't burned it by then, we simply come burn it for him."(Bradbury 59) This is the most important line from this chapter because it is foreshadowing that Cpt. Beatty will become the main antagonist in the book by threatening to burn down Montag's house because he has the book. In the future, I think Beatty will become the main force against Montag, trying to stop him from collecting books. It is obvious that he has been collecting books because he pulled about 20 books out of his ventilator grate. Also, at the end of the chapter, he sits down and starts to read the books that he has revealed that he has. As he is starting to read the books, Beatty is knocking at his door to try and get back in to see that he actually does have the books. This shows that Beattyt will become the main antagonist in the story because he is already trying to make Montag not read books by trying to get rid of his confidence. What do you guys think? Will the main antagonist be Beatty, or someone else?
