The last time we see Tiwari's TASC colleagues, Zoya and Milind, they are left injured and trapped in the rapidly deteriorating chemical factory. Unaware of just how dangerous and destructive a situation they have walked into, Zoya and Milind are unable to call for backup as they are continuously buffeted by bullets from Moosa's accomplices at the factory. When Milind, injured by a bullet, attempts to contact Tiwari, the latter is unable to pick up as he has left his phone in the office whilst going to inspect Moosa's body.Zoya and Milind's survival is crucial at this point as they are the only TASC agents that know that something is amiss at the chemical factory. Hence, to have any chance of disabling the industrial time bomb rigged by Moosa, they must contact their team. The simplest possibility is that Milind calls Tiwari's colleague JK, who is with him at the moment, or one of his other colleagues at TASC, for backup. Of course, whether Milind, who seems to be in a bad shape, even survives long enough to make another call after his first, unsuccessful one to Tiwari remains to be seen. Zoya also is trapped under a barrage of bullets and seems to have exhausted her own but she may be able to call for reinforcements amidst the chaos.
Though there is hope that one of the two characters is able to call for backup, their chances of survival appear bleak — Milind, due to his injuries, and Zoya is trapped, out of ammunition, and cowering from an advancing gunman. Even if they survive the gunmen, the two agents are literally at ground zero of the massive chemical attack. Hence, even if the attack is contained in a smaller area and doesn't destroy the city, it is highly likely that it will kill everyone in the factory, including Milind and Zoya. The fact that the two don't appear in the season 2 trailer doesn't bode well for them either.
