Agree that it's better of they give hints that Raghav is Suraj, it'll make viewers more interested in the episode waiting for their reunion.
I don't think viewers would be interested in watching Sukor's end, even before the 7 year leap, TRPs didn't increase for separation week.
People are more interested in Sukor meeting or saving each other, viewers haven't lost interest in Sukor, TRPs dropped when focus shifted to Anjor and her MU with Chakor.
The only fear is that this is the most that Udaan could get at 7:00. I hope this isn't true and as this track progresses numbers would increase but even if it is so, Colors have bigger headaches than Udaan.
I think Colors are wrong to start 4 new shows in one month, they need to think before commissioning new shows because now it feels they throwing things at a wall and hoping for something to stick.
