Okay, so Iâm on my second watch of s2 and I think people are really being too harsh on Aziraphale. Hereâs the receipts:
1 - He said to Metatron that he didnât want to go back to heaven, he only accepted the job after Metatron said he could take Crowley with him
2 - When Crowley says âIf Gabriel and Belzebu can go off together, then we can [âŚ].We need to get away from them, just be an us. You and me.â, Aziraphale answers âCome with me to heaven. [âŚ] We can make a difference.[âŚ] We can be together, angels, doing good.â He is not rejecting Crowley nor the idea of them being together, he is rejecting the idea of doing nothing to make things better. Heâs saying âletâs be an us in heaven, where we can be together and look after this planet that we both love instead of abandoning itâ
(Of course that he is seeing heaven through rose-tinted glasses, but this is a whole different rant)
3 - The dialogue in the book shop is very similar to S1 when Crowley say they can go off together and let the Armageddon happen: While Crowley wants to run away and save them both, Aziraphale wants to try saving Earth, the only difference is that now Aziraphale recognizes that he needs Crowley and wants to be with Crowley.
4 - Just before EVERY, Crowley says âYou idiot, we could have been usâ, Aziraphale turns away from him to cry. In this scene I believe they are both thinking the same thing âHe might even want to be with me but only on his terms.âÂ
5 - The âI FORGIVE YOUâ scene, he meant âI forgive you for not wanting to come with me and trying to change my mind, instead breaking my heart even moreâ
Aziraphale LOVES Earth and will try to do everything to save it and he knows Crowley loves Earth too, they are not Gabriel and Belzebu who never cared for Earth nor humans. He knows Crowley didnât want to work for Hell anymore and that he is good and he can finally do good without being punished.
Crowley (and the viewers) has a much clearer and realistic vision of how things work, because heaven has already betrayed him. He doesnât want to go back there because he already knows all of its flaws.Â
Crowley is a realist (and a bit of a pessimist), he believes Earth will end because heaven and hell cannot be trusted, so the best solution is to run away while they can.
 Aziraphale is an idealistic, he is going to heaven, he is going to fix the system, Earth will be happy and safe forever, Crowley will realize that and go to heaven after him and they will live happily ever after.Â
SO WHENÂ Metatron said about the second coming Aziraphale REALIZED Crowley was right about heaven, but he still had to try to save Earth instead of taking the easy way out.
SO STOP TALKING SHIT ABOUT THE ANGEL, HE LOVES CROWLEY AND LOVES EARTH AND IS JUST TRYING TO SAVE EVERYONE
