"Birdsong is her Ma-Paa's dream, she can't break their dreams."
I love Sam and Radhikas relationship; it reminds me of my sister and I, big sister protecting her brat
With this said, I bet even though Sam wants to be with Arjun she is going to realise she is in love with Neil, and she will get to know Arjuns "asli chehra" and am damn sure Arjun knew all along the financial issues surrounding Birdsong and I wouldn't put it pass the cvs to probably make him the owner of Samudra.
For whatever happened in the past, Sam is the one he wants to pay for whomever's sins, or for whatever evils he thinks was committed.
Those that feel all scenes between Arjun and Radhika are romantic, please take your rose tinted lenses off and actually pay attention to tone of voice and body language. Arjun is forming into an all and out villain. And he needs to get rid of the pebbles in his path to reach his boulder so he can push it off the cliff.
Arjun is going to force Sam into whatever he wants and hold her ransom to it and Sam after just winning back her mother's love is going to sacrifice herself for the sake of her family.
