The Pein and Nagato Mystery possibly revealed. 

The original body of Pain was a boy

 named Nagato  who, like 

Konan and (Yahiko) were orphans 

from

One night at dinner, Nagato cried

 because eating together reminded

 him of his family, and later that

 night he ran away with (Yahiko).

 
The two were attacked by a Rock

 chunin, who injured (Yahiko)

. Seeing this, Nagato activated his

 Rinnegan, and killed the ninja, a

 feat that is normally impossible for

 someone who has never trained as 

a ninja or never had any military or

martial arts training. 

This is the picture of the "Sage of

 the Six Paths" he was the only 

shinobi to possess the Rinnegan, let 

along the first. Now, in the article 

above says that Nagato HAS ALSO

 the Rinnegan, meaning that there

 HAS TO BE A 100% connection 

with the "Sage of the Six Paths"

 sice at said in the first article of 

info that "normally impossible for

 someone who has never trained as

 a ninja or never had any military or

 martial arts training" this was 

more than a natural power from 

Nagato but it was like a "given

 power"
