JEAN-CLAUDE VAN DAMME
AS SEEN IN:
"Die Fast, Die Furious"
Replicant and/or clone
Filming a stunt from the roof of the Montecito on a motorcycle, something goes wrong and Van Damme dies.
This can't be the real Van Damme. But everybody accepts that he's dead. Somebody in the Las Vegas CSI had to notice it was a real body or not.
Therefore, it had to be a clone or some other kind of replicant. And it wasn't revealed that the real Van Damme was still alive until after the episode ended.
