I remember him saying that but we don't know if he did. Also that was just a made up romour which we all believed that he would enter as ranbir's brother given vikram in the first few epis post leap said he has two sons and a daughter (the daughter/ ranbir's sister they stopped showing after rhea's b-day party I think). She's irrelevant anyway. After that scene where vikram said he and pallavi have two sons they never said anything about another son. But zee have pulled crap like this before. In another of their shows I watched, tashan-e-ishq, the male lead kunj's mother in the first few epis said he has a younger sister, yet never once did she appear and neither was she ever mentioned after that epi, yet a sister for the female lead turned up out of nowhere despite there having been no prior mention of a sister of the FL.
yeh they got disappeared ranbirs sister who was shown once or twice so how can we say about brother which is not shown yet and only mentioned same goes to sunny. pragya only once asked disha about him but now pragya also left that topic. and not even once purab also asked disha about him
