You and Aziraphale are best friends. He is an angel or a principality, and you are a mortal man.

He and you were in his bookstore tonight. He was sitting at his desk sorting the books he wanted to sell into piles, and you were helping him by putting the piles in the right places on the shelves. Everything was fine and he was happy to help. Everything was quiet until...

There was a crash

You peeked out from behind the shelf, and Aziraphale looked from behind his desk, wanting to see what the noise was. You both saw four men, gentlemen, but very similar to your Aziraphale, except for one man in black. Aziraphale5(Your angel):: Gentlemen, who are you? The angels turned at his voice Aziraphale1:: We are you, but from different versions. It turned out that Aziraphale1 was from the book version, Aziraphale2 from the audiobook version, Aziraphale3 from the musical version, Aziraphale4 from the radio version, but he was the most unlike your angel.

While you and Aziraphale5, or rather your angel, were surprised, Aziraphale1 with his arms crossed behind his back looked at both of you, Aziraphale2 and Aziraphale3 looked at the books on the shelves, and Aziraphale4 looked out the window at the evening.
