Where's 'dar gayi Dr Riddhima' dialogue?

in the promo, they show him coming close to Ridz and saying 'kyun? dar gayi dr riddhima?' .. they didn't show any of that in the episode..

and Atul was kind of conspicuous by his absence. i mean in the background they show him going back while everyone else goes forward.. and he doesnt hi five with Armaan..

but he doesn't seem to ask Armaan to not do it.. or scold him after he insults her
