Kareem is the young college student killed for being a suspected terrorist by Tiwari and his men. Soon after the encounter, when it is discovered that the boy was transporting meat and not weapons, Tiwari is racked by guilt. His conscience is further burdened when the boy is labeled a terrorist by the face-saving government agencies responsible for his death. At one point, he decides to reveal the truth about Kareem but is stopped by his supervisors.
Unable to help himself, Tiwari anonymously informs Kareem's grieving girlfriend Jonali that her boyfriend was not a terrorist. She then follows the events leading up to her boyfriend's death and finds a recording hidden by him moments before being gunned down. In it, he professes his innocence and specifies that it was meat, and not weapons, that he was carrying. The footage also shows a menacing-looking Tiwari in the background, wielding a gun.
Hence, Jonali and her mother, who earlier threatened to go to court for the wrongful death of the young student, now have definitive proof. The matter, thought to be buried by the heads of TASC and the NIA, could open up a can of worms for everyone involved when Kareem's final footage comes to light. More than anyone else, the footage will incriminate Tiwari for an error of judgment that he already feels very guilty about. It is worth considering that with the footage coming out, Tiwari will most likely be fired from TASC, which is why we see him at a different, tamer desk job in the season 2 trailer. However, nothing can keep Tiwari from getting his hands dirty.
