In episode 6 of South of Hell, the main characters are in Purgatory waiting for a bus that will take them to Hell. The main characters escape to a place on the edge of Purgatory and there is a car there that (presumably) will drive them to the land of the living.
The car has a "D" sticker, which I first associated with Germany, but the show takes place in South Carolina and there are no connections to Germany in the plot; it must mean something else otherwise it's a horrendous continuity error. So I must have missed something that explains why a car in Purgatory would have a "D" on it.
What does the "D" sticker signify?
For comparison purposes, here's a photo of an Germany sticker.
