Once upon a time Spike allowed Drusilla to watch too much Nova. She understood it in a insane-quantum-physicist sort of way.
The man said that stars traveled in time, to glow their ghost light post mortem over the earth. Radiant shadows of themselves, they are the things humans don’t see because they are too big and far away. Like portraits of what mere mortals can’t see because they’re too small and close: macro-atoms that vibrate spin and explode.
They say that space is silent but Drusilla hears the stars sing the opera of gods, while sub-atomically angels whisper soft lullabies.
