Fahrenheit 451 post

In the book Fahrenheit 451, the main characters are Guy Montag, Clarisse, Mildred, and Captain Beatty. The main conflict is that Guy is a fireman, and their job is to burn all the books that are in the society, Clarisse has knocked some sense into Guy, and he is now questioning whether to burn or save the books. Guy reacts to this by taking some books from work and choosing to read them. I believe that Mildred is not reliable, and will tell Beatty about the books. I also predict that Beatty will not give Guy any mercy, and will fire him or punish him. Can Mildred be trusted?
