Ranveers next target is Armaan Malik (John Abraham) who was the next responsible behind Sonia's death, and he asks Robert Dcosta alias RD (Anil Kapoor) and his comic assistant Cherry(Ameesha Patel) to introduce him to Armaan, promising him a commission from the profits he and Armaan would make in a fail-safe scheme he has in mind.

Soon, he establishes contact with Armaan Maliks girlfriend, Omeesha (Jacqueline Fernandez), under the belief that she is the sister of Sonia. He tells Omeesha of his plan to destroy Armaan, like he had finished Vikram Thapar, as they both had been instrumental in killing his girlfriend and her sister, Sonia. On her part, Tania also pledges her support to Ranveer. It turns out that Armaan and Omeesha had conned Ranveer into believing that she was Sonias sister so that they could know what was in his mind.
