how i imagine good omens season 3
Aziraphale learns of the plans to be executed by Heaven for the Second coming. And they're not good. At first he attempts reason and bargain, but soon realizes that still, even with being in such a high position of power, Metatron in the end, calls the shots.
So Aziraphale chooses his next tactic: lying. He pretends to go along with the plans, a change fooling nearly everyone but Metatron, who realizes Aziraphale is not as gullible as he thought, and suspects Aziraphale's time on earth has completely corrupted him after all.
Aziraphale gathers as much intel as he can, in hopes he could get it to the only person he can trust(the persons who's trust he's betrayed): Crowley. He tries to come up with a plan to thwart the second coming, sneaking around heaven, planting the seeds to make this happen. This starts with stopping the starting catalyst for the second coming: a falling angel.
Metatron requests(threatens) he'll choose someone to fall if Aziraphale doesn't. The plans are already in motion, on X day, Heaven will open a portal down to Earth. Hell will simultaneously open a portal directly beneath connecting Earth to a great bath in the center of Hell filled with burning sulfur. As the angel hits the ground, Hell and Heaven together will rise all from the dead, and second coming will commence (note: never read the christian bible in my life so nothing written will be accurate to this).
Crowley, still on earth, finds this all out through other means. Muriel, who now runs the bookshop, cheerfully informs Crowley of the second coming and of the devastation that will be wracked upon humanity (Crowley forgives her naivety and corrects her on the matter). Not knowing what else to do, he turns to Anathema to see if he can gather more info. He learns of Agnes' prophecy continuation, and against Anathema's wishes, miracles it back into existence. A line sticks out to him.
When heaven nears sulfur all will come to unrest
Crowley returns to the bookshop to inform Muriel of his findings. The bookshop is in disarray, as if there was a struggle. Sensing trouble he immediately exits the shop to search for Muriel.
On the day of the fall, Aziraphale dawdles deliberately. He tells Metatron that there is no way he can pick anyone for such a thing. As Metatron and Aziraphale talk, from beneath his desk, Aziraphale writes down the coordinates that the portal will open to, and miracles it down to earth, to Crowley.
Metatron informs Aziraphale that he figured Aziraphale would not be able to complete this task, and introduces the chosen scapegoat. Aziraphale widens his eyes to see its Muriel, handcuffed. His calm persona betrays him and he gets into an angered frenzy, telling Metatron he cant. But he does. What aggravates Aziraphale further, is that Metatron tells him Muriel deserves it, for deceiving heaven and working with demon Crowley.
Crowley is meanwhile driving to the coordinates that have suddenly appeared into his hands. The penmanship is messy, as if hastily done, but he recognizes Aziraphale's writing all the same. He's spent weeks feeling betrayed and angry, but all he has now is this terrible feeling of dread in his gut. Worry for his friends, for his angel.
Muriel's wings are revealed into corporality. But before their wings can be tied to then be unceremoniously tossed in the portal, Aziraphale magics the handcuffs away and pushes Muriel into the hole, yelling at her to fly. There is a struggle. Aziraphale gets knocked in the head. He's dizzy, he thinks he's bleeding, and he realizes he's falling out of the portal too. Instinctively, his wings materialize as well, but he's too stunned to use them, and their weight propels him down.
Aziraphale is falling, Muriel is chasing after him but he's falling too fast. Crowley sees the portals from his car and curses. He's too far. He wont get there in time. He opens the door and black wings sputter into existence and he takes off. He's never flown so fast in his life. He's desperate. He won't lose his angel again. Crowley nearly reaches him, just as Aziraphale falls through the second portal right down to hell. Crowley dives right in, the portal closing behind him, which prevents Muriel from following.
He barely manages to grab Aziraphale in time before they'd have hit boiling sulfur, and crashes them straight into a very startled crowd of anticipating demons. Crowley doesn't know what to do, Aziraphale is barely conscious. He miracles a cloud of dust to cover them, and a pile of cement to crash down on the other side of the room as a distraction. Their wings dematerialize. He slaps Aziraphale awake and drags him down a hall. Aziraphale clings to his side as they make it into a small crevice to briefly take respite in.
Aziraphale is still disoriented from the fall. Crowley notices the blood on his forehead and wipes it away. Before Aziraphale can say anything Crowley does first.
"Angel, I'm going to get us out of here. I promise. But we can't have you looking like this. Make yourself useful and turn into something... more fitting? Just until we get out of this place."
Aziraphale looks at Crowley, nods, and then closes his eyes. His already tattered suit turns black and gray, and his white hair, already thoroughly dusted grey from the fall, becomes darker. He rummages through Crowley's right pocket and finds an extra pair of shades, which he puts on.
"Is this alright?" Aziraphale asks.
"Beautifully demonic." Crowley replies.
They leave the crevice and venture through the hallways of hell. They slink to the side, avoiding the gazes of other demons, lest they look too long. Crowley leads and Aziraphale follows, a hand clinging to the back end of Crowley's jacket. They turn left, then right, then right again, making all these twists and turns until they eventually make it to a backdoor entrance to Earth. In great relief, they make it out. They end up a ways from the now closed portals, close to Crowley's car. Muriel isn't to be seen, so they get in the vehicle to try and find her. Crowley looks through the prophecies and finds a clue that would lead them back to Anathema. As they ride Aziraphale informs him about heaven's plans and they formulate some ideas to stop the second coming. Midway through their conversation, Crowley speaks up.
"You really hurt me, Angel."
Aziraphale pauses. His eyes lower in guilt. He apologizes, and asks Crowley for his forgiveness.
