Crowley and Aziraphale were inside A.Z Fell n Co having some random discussion until Crowley was about to leave it was night and he opens the door to leave but he sees a small package and raised an eyebrow and taps it with his foot as it made a noise and Crowley calls out for Aziraphale, he comes along and goes to open the package and sees you, a small baby inside the box with a black key and cushioning around you
