Ok hear me out on this- the scene where the Doctor is reunited with Rose after she gets from the parallel world. The Doctor sees Rose after Donna hints at it and both he and Rose run towards each other and gets shot by the Dalek.

Now imagine that scene with Aziraphale and Crowley post season 2.

With Muriel in the place of Donna and Metatron in the place of the Dalek lol.
