When Sadhana has just died and visited Ragini the Doctor comes out to say that it's a miracle she's getting better and Ranvir goes in to see Tamanna and Ragini and he has a dialogue with them...
He basically says to Tamanna that her mum scared him to death and that it's not nice and that one day he'll make her go through the same pain of possible separation and then she'll know what it felt like.
I found that quite ironic and although it was said mildly i think it was a deliberate interjection by the CT's. It made me think that perhaps they have decided to use the storyline of that film 'Dil ne jise apna kaha' the whole idea of Anmol having Ranvir's heart or something along those lines.
