I’m old enough to have been a fan of Buffy, but didn’t watch TV back then. I also enjoy some modern pop music but, in the vast majority of cases, have never seen the artists. I’m also terminally bad at faces even if I have seen them (I’ve had to ask my wife whether a picture of her was her; she took it well).
I did actually recognize Alyson Hanigan, since she has a few distinctive expressions and features, but had no idea of the rest.
All that said to say: thanks for the explanation; me not getting the joke or reference doesn’t mean it was a bad one.
Well, most nights, sunlight still bounces off the moon before it hits the earth and its inhabitants. This could imply that the sunlight is only dangerous to a vampire prior to interacting with another solid object. If one is willing to assume that the lens and its various filters qualify as a solid object, that could explain the lack of death.
Presumably the only reason they don’t employ this loophole on Earth is because an astronaut just walking around would draw unwanted attention.
Alternatively, perhaps the vampire keeps its back towards the nearest star at all times.
