It was so obvious from today's show that Yash / Joker is doing this to get back Roshni and probably even rise in DD's eyes and get her business - may be.
But can Siddharth ever trust his only soul-mate and share his secrets... how would he react if Roshni hides something from him?? The only thing she did was her preg and that hide made him so uncomfortable so imagine Roshni's state of mind where her partner keeps lying (right from name identity, not letting her know on RV, accident in Bangkok, divorce despite confessing love an evening before, shiv patel story - well let's just say numerous times!!)
Can he ever confess what is in his heart... he has lost his relations so many times... i agree that he is the hero and therefore solves everything, intacts his relationships but threads which have a knot cannot be passed through needle test!! he will loose every relation sooner than later with these secrets and no confessions
Roshni on the other hand tried confrontation but is holding a bullet to your head only medium to get Siddharth say the truth?? if so, then Roshni know what to do.. only she doesn't know the severity yet!!
sorry for random post but felt like writing down.
