In the season final of Supernatural (season 8), we see:
How all the angels fall down from the sky. And they all look like humans with wings (Which are lost during the fall).
We've seen our share of angels in the past and we know that they don't look humans in Heaven, they just posses human vessels when they come down to Earth, so my question is:
How come the angels falling all look human? Is this just a visual resource? A mishap (hardly doubt it) or is there another explanation?
Sorry for keeping the question as a spoiler, but I think it needs to be covered.
