* Here's an unconventional one: A man (I think he's a janitor) takes a lunch break in a grey, artificial plaza with a sickly tree in it, thinking about deforestation. Suddenly the tree starts to grow, sending out roots and tendrils to the cracks in the paving, and the janitor climbs up on a branch and helps the tree break through the glass ceiling, laughing aloud as it begins to rain. My description does not do it justice.
** Seconding this. In a book full of things that made me smile, that one scene ''still'' stood out. That and the one mentioned below with the soldier.
* [[spoiler:Crowley]] rushes into the [[spoiler:burning building]] to save his ''[[spoiler:friend]]'' - to save ''[[spoiler:Aziraphale]]''.
** And relatedly, that when Aziraphale figures out where the Apocalypse will begin, his first instinct is to call Crowley.
-->He ought to call Heaven. He ''wanted'' to call Crowley.
* Sergeant Deisenburger being sent away... to the farm where he grew up, and it seems like he's not leaving this time, especially when he hangs up his gun and stops talking like a soldier.
* "The tape he put on was ''Handel's Water Music'' and it stayed ''Handel's Water Music'' all the way home." The perfect finishing touch to everything that had come before.
* At the end, Crowley and Aziraphale get their dinner at the Ritz. And meanwhile, a nightingale sings in Berkley Square.
* The way Crowley and Aziraphale deal with each other towards the end, e.g. how hands-on they are with each other - Crowley grabbing Aziraphale's arm and whispering to him, Aziraphale laying a hand on his shoulder, etc. Aziraphale expresses genuine sympathy for Crowley's ruined car, whereas ''Crowley'' sincerely commiserates on Aziraphale's lost books. This is an angel and a demon by the way, representatives of two opposing sides that hate each other so much that the mere tension between them keeps trying to bring about the end of the world.
* Crowley is clearly stressed over the idea that Hell could crush and torture him into nonexistence any time they liked, and while he seems to occasionally take it out on humans by making ''their'' lives somewhat miserable, he's still willing to lay his head on the chopping block (despite express warnings by Hell that if something goes wrong, he will be ''done for'') to try and prevent the Apocalypse rather than let all those people die for some cosmic chess game. There's also the fact that the war would mean either his own death or the death of his best friend.
* At the end, Crowley and Aziraphale [[spoiler: choose to stand together in a futile battle against the Devil to try and postpone the inevitable rather than watch him and Heaven wreak havoc on Earth.]]
* The way that Adam Young's love of his home is depicted is very touching, especially when it brings him back from the brink of bringing about TheEndOfTheWorldAsWeKnowIt.
* Likewise the fact that an idyllic childhood and life among humans (without any celestial or infernal intervention) was able to overcome Adam's demonic nature and instill a love of the world forms the core of the book. Choice and the potential for good and evil in all of us is a big theme of the book best exemplified in truly heartwarming fashion by Adam Young.
** A good example: when Adam meets Anathema, she invites him in, gives him lemonade, and spends the afternoon telling him about paranormal things, which fascinates him to no end. He wants to do something nice for Anathema, just because he likes her, so he uses his powers to shut down a nearby nuclear power plant (which he knew she didn't like).
*** To add to it: he doesn't shut it down exactly. It's still running perfectly, producing exactly the amount of electricity it ought. It's just that ''all of the radioactive material that powers the plant has vanished''.
* The International Express postman's been delivering items to the Four Horse Persons throughout the entire book and having just finished with [[spoiler: Pollution]] realizes his next stop is [[spoiler: Death]]. Before he goes to meet him, he leaves a final message for his wife saying: I love you. It's sadly very sweet coming from a man who's been helping to reequip the major players of the Apocalypse.
** Which makes his [[spoiler: resurrection at the end of the book all the sweeter. Gosh, but it was good to see him alive.]]
