Crowley: I wanna sleep for 40 hours.
Aziraphale: You know that's called a coma, right?
Crowley:
Crowley: That sounds so refreshing, I could totally go for a light coma right now.
So, you know that new theory that Azi was controlling the Bentley at the end of S2E6? And that he made the Bentley play the song?
If it's true, it means something very heartbreaking, see:
Nightingales are associated with mutual love, it's said that if you're confessing and you hear the song of a nightingale outside, it's because the person you're confessing to feels the same.
Crowley confesses and not only do no birds sing, but Azi remains firm on his decision of going to Heaven, so, of course, Crowley interprets this as 'he doesn't love me back.'
But when Crowley is watching him leave, either for safety or to see if he'd change his mind (Book says Crowley is optimistic, after all), Azi can't walk up to him or say anything, since Metatron is there, so he does one last thing before he departs. He plays the song on the Bentley.
When Crowley enters the Bentley and hears it, it's truthfully Azi telling him directly, 'I do love you back, I do feel the same.'
But of course, Crowley turns off the song.
Since, to him, 'If you truly did, you wouldn't have left me.'
Good morning
