Barkha may have been good. I actually was interested in post leap only due to AvNeil so cannot comment on Barkha. But CVS you have fabulous post leap characters that you have not fully utilized. Why complicate things by bringing yet another character from dead. The last time you did this with Juhi, NK deteriorated. Poor AvNeil are having to work hard to bring the TRP up again.
A simple story is far more interesting than a complicated one. Why mess up AvNeil story to insert Ayeshama. Neelama was the biggest part of Avni's growth. The mother daughter equation is fabulous. Please keep it simple.
