I believe it's body doubles or masks as well in this case. I also believe they've been cloning humans for decades. There's no way it just all went away because of ethics, these people have no ethics, morals nor do they care about laws.

not a clone, just someone who looks like him.

Who thinks it's actually cloning versus masks doubles?

Cloning requires accelerated growth or planning roughly x-years old ago. If cloning, how long does it take to grow one?
