The 'injured' Tiger, aka Salman Khan, is sitting next to his senior, who's advising him not to kill anybody this time around. He says, "Tum jis mission pe jaate ho, koi na koi maara jaata hai. Tiger is mission mein tumhe sirf observe karna hai. Please yahan kisi ko maar mat dena." (You killsomebody or the other when you embark on a mission. Tiger, you have to just observe keenly in this mission. Please don't kill anyone)
The attitude of out Agent Tiger is clear from this opening shot - he's injured, he's angry and he wants to kill.
The fight...
