Gunny.....complex character

ok so Gunnys is new "bachha" of Gehlot who has been sent to VDC to kill Naina.....If Gunny is indeed a assasin who works for Gehlot....then how come he saves Ali from Bhargav..saving Ali was none of his business...

I read from the one of the posts here that Gunny is on a Govt. mission..then how come Gehlot does't know this....he is the most powerful person in the parliament(as per Abhimanyu)....and he sent Gunny 2 VDC to kill Naina....

anyways am looking forward to scenes between Naina and Gunny...both r powerful, intense characters.....will be damn interesting...If Naina has stood her own against Capt Rajveer(initially, when both did not know abt each other's identity)...am sure Naina will very well be her own against Gunny...she will not need anybody's help.
