There's not a whole lot to support this, but they're seen conversing, quite civilly (all things considered) and obviously not for the first time.
It makes Michael being the one to pour the holy water used to execute "Crowley" dramatically appropriate, as well. She's probably eager to kill the guy who murdered her friend, but has to keep it under wraps.
This is based on Crowley's hypothesis that God's "ineffable" plan is for the real final battle to be between Humanity and it's supporters and the combined forces of Heaven and Hell. Assuming this is the case, then logically those events would wind up being covered by the show.
All the other children have backstories but Brian isn’t given one. His name could be a nod to Life of Brian, where he is the messiah.
- It isn't a nod to that. The name is from the book, which eventually reveals that the other baby at the hospital was adopted into Tadfield, and he's the leader of The Them's rival gang, the Johnsonites.
- With the series being a Pragmatic Adaptation of the book, series!Brian could be a case of Composite Character.
- It isn't a nod to that. The name is from the book, which eventually reveals that the other baby at the hospital was adopted into Tadfield, and he's the leader of The Them's rival gang, the Johnsonites.
- Or it shares a community with World Of Darkness, where the Almighty is also a woman, who holds both angels and demons for fools and has her own plan.
Getting bored as time goes on, or deciding to do more good, Crowley assumes the name "the Doctor", and starts taking people to more places and worlds. Maybe he also uses the place Galilee as inspiration for the name of his "home planet", Gallifrey.
It is also mentioned that the Earth was only a few days old by the time Crowley (then-named "Crawley" caused the fall of man) and by then the dichotomy had been established long enough for Aziraphale and Crowley to assume things about each other. If Genesis is accurate, then that means that the universe was created and the War in Heaven occurred all within the span of a week. It could be possible that the afterlife operates in a Timey-Wimey Ball or the creation of angelkind and the fall of a chunk of them occurred before time and the universe were even invented.
The book makes a clear point that angels are Always Lawful Good, demons are Always Chaotic Evil and humanity's potential for both being why they are so special. While their behavior hint that the dichotomy of "angels are good" and "demons are evil" are based around Cultural Posturing and Nature vs. Nurture (God herself states that they were "cut from the same cloth"), their weaknesses against Holy Water and Hellfire are what illustrates that their differences run down deep into the genes (or whatever it is they have).
This theory exposits that God created what would eventually become the Fallen Angels in their natural states. All of their wings were black, their behavior would eventually be labeled "bad" once God made the difference between good and evil and "holy water" and "hellfire" were called something else before the line between "holy" and "unholy" was drawn. It would be like different breeds of dog or the difference between dark chocolate and white chocolate. The differences between them would be distinct enough that distrust would occur between the two factions - perhaps even some form of prejudice - and all it took was a handsome, charismatic populist among the soon-to-be-fallen angels to inspire an uprising and urging his brethren to embrace their natures that they didn't even know they had.
It would also make sense why the rebellious angels would be so keen on continuing to serve Satan even after he led to them being thrown out of Paradise, as they would have as much beef with their "good" counterparts as much as they do with God and they are allowed to be themselves in a place like Hell.
- This is an interesting idea, but some of Gabriel's dialogue to Aziraphale makes it clear that in the Good Omens timeline, the War in Heaven happened long before the creation of Earth (and, indeed, Heaven and Hell appear to believe that Earth was created for the purpose of serving as a battlefield on which to "settle things" between the two factions).
- He did in fact suggest this on social media but from the way it’s phrased it comes across as a joke
This fantastic essay ( [1] )goes into 36 pages of depth, but in summary: Background things things go missing when they shouldn't, Maggie is written weirdly next to the rest of the cast (the point that she feels more like a character than a person), and the new flashbacks often feature a notably meaner Crowley and a good-er Aziraphale. "Bildad the Shuhite" is also dressed wrong for Crowley of that era... Almost like someone knew about the shades being a constant, but didn't know when he started wearing them. Curious.
Every Archangel (Gabriel, Uriel, Michael) has appeared besides Raphael, who hasn't even been mentioned. This suggests that either, 1) Neil Gaiman didn't want people mixing them up with the Ninja Turtle, or 2) they're being saved for something.
Crowley's name presumably wasn't Crowley or Crawley before he fell, and isn't established in the opening flashback to his pre-Fall days. He clearly had a decent rank as an angel; Dominion is the highest of the Middle Order, while Principality is the highest of the Lower Order, so Crowley once outranked Aziraphale by at least an entire order. Crowley's able to open a file full of highly sensitive information because the the passwords haven't changed. He doesn't say Dominion was his rank, only that he had that rank or higher. So... what if he was, in fact, an Archangel?
Just a guess, but it would explain his being entrusted with important jobs, such as tempting Eve, delivering the Antichrist, terrorising Job and acting as Hell's representative for 6000 years with very little oversight. Crowley's also the least "mutated" demon and also seems to be, specifically, the only one who can stop time.
It might also explain the Running Gag of Crowley failing to recognise angels and demons he's apparently worked with previously, to their frustration; a fallen Archangel would presumably be A Big Deal, so it's the equivalent of someone bugging a celebrity they once encountered.
Because it's too sad otherwise, okay?
Seriously, though, watch him when Metatron mentions "The Second Coming." He does not like what he's hearing, and looks at Crowley standing by the car as if he'd very much like to jump in that car with him and drive away. Why doesn't he? Because Metatron would probably smite him before he reached the car, and then Crowley for good measure.
Even if he didn't, the Second Apocalypse is still going ahead. The previous head Archangel (Gabriel) passing on Armageddon 2 didn't stop anything happening; they just fired him and got someone else (Aziraphale). If Aziraphale passes too, they'll just find a third candidate, and that person might be on board. Whereas if Aziraphale seems to be on board, then he can act from the inside to prevent whatever's happening. That look is Aziraphale realising what a terrible mess he's just landed himself in... and that he's the only one who can fix it. And that creepy little smile midway through the credits was him putting on the mask.
Metatron mentioned his insider knowledge of humans being a factor in his appointment, so it may revolve around spreading misinformation. This will be complicated by the fact that espionage isn't exactly Aziraphale's strong point; remember what happened with the Nazis. So Crowley, having realised what's happening, will have to rescue him again.
In season 2 flashbacks, Angel-Crowley's pre-Fall role in starting the stars spinning suggest that a name meaning "Light-bringer" would be fitting. Crowley mentions the name Lucifer once in season 1 while monologuing aloud, but Crowley was so drunk at the time that it's not impossible he was talking about himself.
The implication is that there's more to that breakup scene than we saw. At some point, presumably during the kiss, Crowley froze time so he could fill Aziraphale in on the "second Coming" plan he heard about in Gabriel's file, and they hashed out a plan. We'll see that part of the conversation in flashback form in Season 3.
That would explain the creepy smile on Aziraphale's face midway through the credits, just before his and Crowley's splitscreen blurs out; his cover persona has kicked in. After blurring, Crowley's footage remains consistent, clearly still showing him driving, while the background of Aziraphale's suddenly darkens even though he's clearly still in the lift, representing that he's changed for the darker. It also explains why he keeps looking at the clock before he leaves; he's going to Heaven, why would it matter what time it is in one city on Earth?
Then Crowley and Aziraphale combine their powers for a miracle to hide Gabriel/Jim. Aziraphale and Crowley both try to create the tiniest, subtlest half-miracle together to avoid detection…and by so doing they create an impenetrable disguise and set off Heaven's alarm systems with a miracle power spike strong enough to raise 25 people from the dead. Crowley and Aziraphale have performed miracles around each other frequently, but this was seemingly the first time they joined their miracle powers together. And together they immediately hit gamebreaking juice levels without trying.
No wonder Heaven and the Metatron want to separate Aziraphale and Crowley or to bring them Upstairs under close heavenly control. If Crowley and Aziraphale can really generate this much miracle power together, Heaven will NOT want them running around working together as unsupervised loose cannons on Earth.
