Agree with all your points except that of Purvi telling off Ovi. Ovi over-reacted as always. She jumped down Purvi's throat even before Purvi could say anything. And in her defense, Purvi was right in telling Ovi not to leave the baby alone especially on the edge of a bed. Anyone, not just the natural so naturally (pun intended) anxious mother would have said and done the same.
Purvi is an idiot for giving up her baby and the baby will hate her for having given her up to a totally unstable mother. But that apart, I don't like Arjun and Ovi as a couple either, they just don't jell for me. I am happy too that Purvi is finally beginning to see the good in Onir.
Alas, I have no hope for Arjun, they have made him into a devdas almost. Poor Rithvik.
