Hi, yesterday's episode was all Devakshi, both were broken, only way Dev could "hold on" and see her with someone is by drinking, that was his only resort and way out to surpress his sorrow.
But what Sona did was very wrong. Its she who agreed for the engagement, she was neither emotionally blackmailed by her parents nor forced, its she who agreed to move on, but she was not sincere, the whole time during the engagement, she was looking at Dev, and when he fell, she just left her hand from Rithwik and ran to him, She stake not only her family's honour but also Rithwik family honour.
Rithwik family were more than welcoming Sona into the family despite her past, Rithwik was very understanding, but Sona just insulted everyone during the engagement, that was not right. She has all right in her life whether she wants to move on or stay there, but she had no right to insult Rithwik's family.
Here we have Dev who listen to his Mum till willing to sacrifice his love, on the other hand, we have Sona, who just walk past her family without thinking twice of the consequences.
Sona and Dev are both indifferent, both have flaws in them, but what Dev did only affected his family, but what Sona did affected others too, and thats not fair, so Sona is not in a position to lecture Dev on anything.
I really hope that Sona goes back and gets engaged, then its Rithwik to let go of Sona, a nice and understanding closure.
