Was re-watching some old episodes when I caught this. In episode 41 where Manik trips Nandu and she hurts herself, he panics when he sees the blood and silently gestures (ever so subtly) to Dhruv to attend to her but Dhruv, who initially jerks when he sees Nandu fall, ignores the signs as if to say, 'You did it, so you attend to it'. Manik hesitates for a millisec and moves to attend to her but holds back when Cabir applauds him saying 'Manik Malhotra is back'. With his reputation as a monster at stake Manik stays put.
So it appears that Dhruv's resentment at being made Manik's clean up man started way back then. Yes, he punched him even before that but that was because he thought he had sent the goons against Nandu. I think this was the first instance he openly refused Manik to clean up his mess.
