TFS Donny, hugs!
I don't think it's true that other stories are on hold because of Abhigya, the CVs know very well that the TRPs are very high right now and this is what the audience wants to see. I'm sure if the TRPs weren't doing good, this track would have ended sooner or others would have been brought in.
CVs have chosen to do this, if they wanted they could concentrate on all other characters individually or group scenes as and when they wanted.
That being said, I don't get a good feeling about Purab going to get them, hope he doesn't put himself in harms way now. The tracker watches being introduced and now he's going. Kidnappers are dangerous and I'm glad cops are on the trail.
