becoz in bengali literature a famous character is found named Saddashiv...who joined Shivajis army in the age of 14
as he was a kid so Shivaji used to take privilage of his age and thus used to sent him in various adventurous work
and in our teenage the adventures of Saddashiv was very popular among us
Sadda was most trusted one of Shivba's army...jijabai loved him as her own son...Shivba used to depend on Sadda too
but i never found any reference of Sadashiv in history...so i considered Sadashiv as an immortal creation by legendary author Sharadindu Bannerjee (the creator of legendery detective character Byomkesh Bakshi too)..
so when i saw the kid joining shivaji's army and getting a spy's responsibility i was surprised
though his story in the show is a bit diff than saddashiv of bengali stories..but everything except that was matching to our Saddashiv
i am surprised how an imaginary character of bengali literature got life in this show???the show has no connection with Bengal..is it coincidence??
