- Anytime Crowley laments his demonic state is rather saddening, especially considering it was over 6000 years ago and he still hasn't gotten over it.
- From the second episode we get this:
Aziraphale: May you be forgiven.Crowley: I won't be forgiven. Not ever. Part of a demon's job description. Unforgivable, that's what I am.
- In the third episode, we get this during the argument between him and Aziraphale:
Crowley: I only ever asked questions. That's all it took to be a demon in the old days.
- Later in the fourth episode, after he considers his options where he could go, there's this:
Crowley: I never asked to be a demon. I just minded my own business one day and then "Oh lookie here, it's Lucifer and the guys!" [ ] Next thing I was doing a million lightyear freestyle dive into a pool of boiling sulphur!
- And finally in the fifth episode, drinking himself senseless, thinking Aziraphale had been killed.
- In relation to the above, Crowley's appeal to God as he contemplates leaving for Alpha Centauri. Yeah, he's a demon, but in that moment he sounds like he's praying:Crowley: Great Plan? God, you listening? Show me a Great Plan. Okay, I know youre testing them, you said you were going to be testing them. You shouldnt test them to destruction. Not to the end of the world.
- Crowley is genuinely horrified that God plans to drown everyone in the Great Flood.Crowley: Not the kids. You can't kill kids.
- Even worse, he comments that this is something his side would come up with, not the 'holier-than-thou' Lord. The fact that Aziraphale is so apathetic to the whole issue (or at least is trying to pretend to be) makes the morality of the entire situation even more horrifying.
- The scenes are made even more poignant for a Doctor Who fan as Tennant's Doctor was one of the Doctors who believed they destroyed their own homeworld of Gallifrey and spent one terrible night counting each and every child that was living on Gallifrey at the time. Later companion Clara once told the (Twelfth) Doctor that, if he tried to go evil, his reign of terror would end with the first crying child. This seems to apply to Crowley as well.
- Jesus's crucifixion, though a brief scene, is shown in pretty graphic detail, with Jesus sobbing in pain - while asking his Father to forgive his murderers - as he's nailed to the cross. The humor in the scene is also deliberately understated to match how somber it is. A bit meta, considering that Christians were angry enough at this show without it trying to make the Crucifixion seem funny.
- "Someone's killed my best friend! Bastards! All of you!"
"Oh, Aziraphale...I'm sorry. It burned down."
- Watching Crowley stoically stride out of Aziraphale's burning bookshop after the above, and drive away looking possibly the most shaken we have ever seen him, is one heck of a gut-puncher. (And to the outro of "Somebody to Love", no less.)
- Along similar lines, David Tennant's heartbreaking line reading of "I lost my best friend..." when Crowley tells the discorporated Aziraphale why he didn't go to Alpha Centauri.
- The whole scene between Crowley and a discorporated Aziraphale is pretty bleak. Crowley's in pieces, Aziraphale's full of regret, and even though Aziraphale manages to reassure his friend that he didn't get Hellfired out of existence, he's still stranded in limbo and unable to be of much help. Then Crowley has to break the news that the bookshop was incinerated, devastating the angel. Mr. "I'm not nice!" Crowley's voice breaks as he tells him the news.
- The music reinforces the sense of melancholy — called "Is That You?" it's a sad little piano piece that reinforces that the leads are at their lowest point...before Crowley reveals that he rescued the prophecy book, the music perks up and the pair realise that they're not beaten yet.
- The destruction of Crowley's car. Yeah, it's just a car, but the words "You were a good car, rest in peace" is delivered with intense grief.
- The death of the deliveryman is just as sad as in the book. He leaves his wife alone on the weekend to deliver the packages (despite her pleas with him to stay with her), and when he gets to the instructions for delivering a message to Death, he writes "I love you Maud" on a piece of paper and then does as he's been asked.
- In order to summon Death, you need to take a life; which in this case was his own. Thankfully, after Armageddon is averted, his timeline is reset to him being alive again, just after delivering all the parcels.
- Newt and Anathema reach the radio equipment and find a bunch of messages from people all over the world trying in vain to stop the war. No one wants to fight and recognizes war as a mistake, and are only unable to stop the bombs from going off due to the Horsemen preventing them.
- Aziraphale and Crowley's situations in themselves are pretty sad, even before their respective Head Offices really start laying into them. Aziraphale is treated as an oddity as best and with sneering contempt at worst — nobody seriously thinks that he has anything worthwhile to contribute, even though he's the one angel with real experience and knowledge of Earth and humanity. Meanwhile, Crowley's simply too decent to fit in with his fellow demons, and his obvious need for camraderie, respect and freedom is extremely unlikely to be met by the denizens of Hell. In both cases, their affection for humanity and the mortal world is regarded as a serious personality flaw, and their colleagues avoid them wherever possible. No wonder they stick so closely together - each is really all that the other's got.
- An extra kick in the gut is that, despite their fondness for humanity as a whole, neither particularly seems to go in for forming close friendships with humans (presumably because of the difference in lifespans). Crowley and Aziraphale have only recently begun seeing each other on a regular basis — prior to the 20th century, they dipped in and out of each other's lives. It paints a fairly lonely picture: ostracised by their fellow immortals, separated from the humans they live among, and only the occasional visit from the one person they could probably call a friend.
- Crowley also has the additional obstacle of Aziraphale's Tsundere tendencies towards their friendship. He doesn't hesitate to refer to the angel as his friend, but Aziraphale is less keen to acknowledge the demon as such.
- The fact that Aziraphale still has misplaced faith in the forces of Heaven to do the right thing and stop Armageddon. Even though his fellow angels treat him like garbage, he still holds onto hope that if he can just gather the right amount of information or present his argument correctly, they'll come around. Then Metatron bluntly confirms to his face that Heaven fully intends to fight the war in spite of any chance to avert it, destroying the Earth and billions of human lives all to prove which side is better. You can just see Aziraphale's faith in Heaven shatter in that moment.
- Worse, Aziraphale likely realizes that he kept vital information from Crowley, the one person who is truly on his side, All for Nothing.
