... driven to the brink of frustration, as a last resort, Vedika plays her 'trump card' and blurts out to Priya that she's Ram's ex-girlfriend and waits for Priya's reaction, only for Priya to give a deadpan reply - 'I know', following up with, 'main bewakoof nahi hu. Jaanti hu ki tum Mr. Kapoor ki girlfriend thi. Par main unki patni hu. Tum unka past thi, aur main unka present.'
Vedika would be gobsmacked. Nandini would lose her wits (privately, not publicly) and Priya would simply smile with satisfaction.
(unlikely though. I think CVs are waiting to play this revelation to start their 'separation track' - making Priya think 'sab mard ek jaise hote hain')
