She seems that's it, though Karma has a different plan in mind. At the music-signing, Ruhi gets her gun out, though it doesn't seem to work. AJ and Sheena together publish Reggie's music as their own, and it goes onto becoming a big hit.

Though Ruhi does not know that AJ isn't alone, he also has his hidden agenda with Reggie's ex-girlfriend Sheena ( Celina Jaitly) who is now a bigshot due to AJ. He is placed into the operation section due to liver failure, and then Ruhi plans to destroy AJ's career just like he did to Reggie. Then Ruhi shows up and takes him to the hospital. While Reggie was in the state of dying, AJ takes all his music-notes and beats and flees from the place. One day, AJ finds out all Reggie's secrets and gets him so drunk that he has liver-fail. Getting him drunk, getting him smoking, is all that AJ has been doing to Reggie, and Reggie even loses control and passes out.
