What are the scenes where you can see obviously Beatty's characterization/features?
One of the scenes that tells us most about Beatty is when he comes to Montag's house the day Montag decides to stay home from work after the old woman willingly burned up with her books. Beatty tells Montag how their society came to be and why things are the way they are in their world. This shows us that Beatty knows a great deal of information and a great deal of history. He seems to know a lot for the captain of one firehouse. He also puts down anyone who has notions that are in opposition to the government's ideas and ways. It is clear that he is aware Montag has a secret book or a stash of books. Another scene that tells us a great deal about Beatty's character is before Montag kills Beatty. Beatty tells Montag that books contradict one another, they lie and confuse people making them unhappy. Beatty stresses this idea so much, we get the impression Beatty is trying to convince himself as much as he is trying to convince Montag. Later, when Montag realizes that Beatty wanted to die, we see that Beatty might have wanted death over life in their repressed society.
