"It was the black angel, if that sweetens the pot for anyone."
There are a lot of spare eyes in the Night Vale fandom, aren’t there? See I like to imagine the practical function for two sets of eyes like this would be like. When the top pair of eyes blink, the lids of the bottom ones pull upwards and open. When the bottom set blinks, the top set opens.
Which would mean the angels are always watching (8‿8✿)
