There is time for every thing. Satoshi never heard of you. Satoshi is a Time Traveller. He has come from your future to the present to reform the plutocratic economic system. He has come with Bitcoin and Blockchain. He is about to introduce the Justifiable New Economic System to the World Officially. Bitcoin and Blockchain experimentation is successfuly completed.
This was the first voice of Satoshi,
"I am Satoshi Nakamoto, I am a Robot; I am not alone, I have a twin brother his name is ........... ............ and a Grand Father; His name is .......... ....... . ". Your riddle of the Twin brothers is about good and evil.
I can't believe you just out-riddled me.

There is definitely a time for everything under the sun.
So then, let me ask you, Mr. Robot: Who is the Grand Father? And is Satoshi's twin brother, Thomas?
The answer to my riddle can definitely be about good and evil, light and darkness, truth and deception.
Edit: Is Satoshi's grandfather, John McCarthy?
