In this scene, Montag has just burned his home. We learn that Mildred turned him in, but that he was screwed from the moment he read the poem to Mildred's friends.
Was it my wife turned in the alarm?
Yes, but her friends turned one in earlier, and I let it slide.
Montag, after killing Beatty and running away from his house, arrives at Faber's house to seek some sort of comfort. This moment is right before Montag is let in, and Faber acts as a mentor to him. He has done a horrible thing, but Faber still lets him inside.
Faber?
...
Montag is trying to escape the Hound in the river after leaving Faber's place. The hound tracked him down to this spot, and if Montag can evade the Hound, then he will be free. Meanwhile, Faber has fled the country.
I'll save that poem for noon... when we reach the city
Must... Get... Away!
As Montag walks down the rusty railroad tracks towards his uncertain fate, he realizes that he knows Clarisse walked down these tracks before. He does not know his fate, but he knows that he can handle it, wherever it takes him.
Somehow... I just know that Clarisse McClaren has walked down these railroads many times...
In Montag's imagination, he sees Mildred oblivious to the bombs just dropped on the city. Instead, she is listening to the parlor walls, and the seashells in her ears as an attempt to escape from reality.
With those nasty books gone, I can finally relax...
Montag has finally met like minded individuals who think that books shouldn't be burned, and together they watch as the city is bombed. When day breaks, they will go to the ruined city and attempt to get people to join their cause.
