Shiv was a sniper who worked for RAW during Day 1.
On Day 1, Shiv was sent to Eden Park with Saxena to lead the backup for Jai Singh Rathod's meeting with Deepak Patil. Shiv greeted Jai and agent Kabir when they got to the park, and Saxena went through the position of the team. They then covered Jai as he met with Deepak, but when Deepak fled from the meeting Saxena shot him dead. ("5:00pm-6:00pm")
Deepak's body was taken away and Jai confronted Saxena, who told him that he would cover himself in his report of the incident. He then left the park with Shiv, Rai and Giri. ("6:00pm-7:00pm")
