I happened to catch part of an episode of Cold Case. It started in “Sunnydale, California” in the fifties.
Is there any chance at all that this passed through the review process without at least someone catching the Buffy reference?
The episode was rather horrible, since it revisited what we did to Japanese Americans during World War II. Pretty horrific. You might say that the episode argued that the hellmouth covered a lot more territory in reality than it did in the vampire show.
