The Promo starts with PRC telling all his sainiks that war has begun and there is no reason we should lose.Then it shifts over to a battlefield,after than the senapathi(The dude PRC Calls chacha)goes to Bhimdev and says I wanna join ur army...The voice over talks abt deceit by apno
But guys its OBVIOUSLY prithvi's idea cos the senapathi is very loyal to him and Ajmer,and if u remember prithvi had said :Hum logon ko josh aur hosh se kaam lena hoga".So it must be his idea!!!!
