Looks like the stage is set got Michi breakup because of another misunderstanding over NP relationship. But is Neev's role only in destablising Michi? I think not.
I may be reading a lot into the symbolism thrown in by our famous creatives. But there was this scene which has stuck in my mind where Milsi bring home the Ganesha idol and he looses his balance. Just then Neev comes there and lends a hand, thereby, stabilising the idol. I think this scene should indicate something of what the future has in store.
My own reading is that duirng Milsi's absence Neev will be the one to stabilise the family, particularly help Prachi through the troubled times. Hope Ayesha gets insanely jealous and does her best to win Neev over. This in turn will help stabilise Michi relationship and make it stronger when Milsi gets back. I only hope that Milsi does not misunderstand Neev's help during his absence as if NP want to get back together and end up breaking with Prachi forever.
