And i've noticed one thing, that if you watch it in one go with all the storylines being played out it seems that this whole Sadhna sacrifice and wanting to be loved and eventual death was all planned from the beginning by the CT's.
Obviously not from the start i think initially it was the bond between the sisters and the wonderment of if they'd get married. But after that it all seems to fit in.
If you remember both Ragini and Sadhna participated in Taj concert in the first couple of episodes and both danced together on the song 'Rang De'....and then about 2 years later they again dance but this time against each other. And RS did mention how he's wanted to use the song 'Badaai Ho Badaai Ho' for the last two years. And it eventually was used during Aalekhs engagement.
Mamaji always professed that Sadhna's love and sacrifice will one day be appreciated by people and that they'll learn her true worth but by then it might be too late and lo behold yes they appreciated it but when the time came to make her feel loved she left them for good.
The fact that all this characters being phased out, the actors not giving straight answers leads me to think that this is a purely Creative decision whereby they've had a clear cut plan and have executed it quite well....All the stories are interlinked and all have Sadhna at the core along with the extremely special bond of the two sisters and how they are one soul and cannot bear to be apart.
Maybe i'm clutching at straws, it's really early and i've stayed up watching back to back episodes, but if you guys all think back to all the twists and turns it all adds up.
And i have to say from all the other serials i've watched, Bidaai overall has a really effective way of executing the story twists and arcs in a exciting, interesting and beautiful manner.
