Opposing Forces
"Crowley, you know when I just said, 'Two of you, Deity and the Adversary, facing off.'" Aziraphale whispers under the tree in his bookshop.
"Yea?" Comes Crowley's choked answer.
"Well, do you remember the Arrangement?"
'Of course I do," Crowley whisper-hisses back in a - why are you bringing this up now - tone. "Heaven, Hell, pointless work, cancelling each other," he pauses.
"Oh wait."
"Yes, exactly." Aziraphale answers.
"Here, take my hand."
We are not like them, Aziraphale thinks as he remembers all the lovely moments they shared across millennia, their games, their arguments over who's going to travel this time, about goodness, about their work, their unfortunate sides. About what is possible and what is not.
If he's right and Aziraphale thinks rather might be, the sides will cancel each other out and he will make it into the future. With Crowley. He squeezes his demon's hand. Always his demon.
"But how is the universe back?" Crowley asks when they finally separate from a very, very long hug and he peers out of the bookshop's window into a street that's just waking up into the morning light.
"Um, wait what was the theory... Aziraphale muses out loud, "there was an infinite amount of matter and antimatter and they cancelled each other out, but the amounts were not quite the same and from the rest came the universe?"
"That makes no sense angel?"
"It doesn't? Well. It worked." Aziraphale smiles.
"And Heaven and Hell?"
"Oh I think they will be glad to take a holiday, don't you? And with no one to give orders..."
"Do you think some will want to move here?"
"Like Muriel? Possibly yes, but we will cross that bridge when..."
Aziraphale is swept into another bone crushing hug.
"... the universe is big enough for all of us."
"Angel." Crowley holds on to Aziraphale for dear life again. "I'm sorry I left you fight them on your own."
"I couldn't let you suffer for eternity Crowley. I just couldn't."
