Vyom said he was in USA when all these happened. So most probably this was a work of Rajan. He is the obsessive and possessive one-------- My son should get what he wants kind. Don't know or don't want to guess anything which we didn't see in the serial yet. Vyom said he was in USA and Sharanya came to Rajan for help.
So far we know Vyom and Sharanya were best friends. Don't forget she wrote a lot of things about Vyom in facebook etc...as far as I can remember she told that. May be she was talking about her best friend Vyom. On the first day of college Vyom shook hand with her and when she tok her hand away----------she found "friends" printed on her palm. So this was friendship.
Most probably Madhvi thought this as Love...purani jamana ki awrat! 😕 As a result Rajan murdered Shiv. When Vyom returned from USA Sharanya was about to tell him about what Rajan did ...but before she could ---------they had that accident.
Now what can a friend do after hearing a story from his Dad that a stalker used to trouble his friend and that was so painful that she has to kill herself? Exactly what Vyom did. Especially if that friend is the reason he is alive. Even in SR plan it he didn't show much interest in doing...! Love se jayada woh friendship tha.
So I guess all these confusions were the master plan of Rajan and created by Vyom's mom. We saw Shiv grasped Sahranya's hand today! Is he dead or alive? Do saal tak under ice--------zinda? Isn't that too much! They could make it 2months..although that is also impossible. Indian TV ------kuchhh bhi ho sakte hai. Sadhvi jaisi Ghost Doctor--------who has no idea "dawai kiski liye ...for dead or alive or half dead? 😆 😆 😆 Without seeing the patient giving ulta pulta dawai!
