The Seashell radio that Faber gives Montag is a two-way communication device known as the green bullet. The green bullet allows Faber to speak to Montag from a distance and allows him to hear everything that Montag is hearing. Towards the end of part 2, Montag leaves Professor Faber's home and proceeds to put the green bullet into his ear. As Montag is walking home alone, Faber reads to him from the Book of Job. When Montag arrives home, Mildred and her two friends are watching the parlor walls, and Montag proceeds to turn the televisions off. Montag then insists on reading poetry aloud to the ladies, and Faber pleads with him to reconsider. Despite Faber's arguments, Montag proceeds to read the poem "Dover Beach" to Mildred and her friends, who burst into tears and call in an alarm on him. At the fire station, Captain Beatty attempts to confuse Montag by commenting on the contradicting nature of literature and knowledge. During Beatty's persuading lecture, Faber helps Montag calm down and offers him reassurance against Beatty's moving arguments. Overall, Montag hears Faber's voice and listens to him read from the Bible and offer valuable advice via the green bullet.
