Sorry but I dont agree! Just because they are parents that wont "ruin" their relationship or even Avni. It's clear Avni has not taken up the role of "Mom". Maybe because she robbed form Neil the right to be a Father, she has not disclosed to Mowgli that she is his Mom. He calls her "Jaan Di" just like everyone else. She wont be Mom, coz Neil doesnt get to be Dad! IF he is their child, then that is what I feel she has done.
She has deprived herself the role of being a Mother while being one, because she deprived Neil of being a Father. That doesn't ruin her character, it makes her character even stronger. It's not easy to deny being the Mother of your own chid, especially when the child is in front of you. Only a Mother will understand this feeling.
IF Avni is Mowgli's Mother then she made the ultimate sacrifice for the decision she made to leave Neil and her family. She made sure what they dont get, she doesnt get either. It is worse for her, because knowing she has a child she still doesn't get the "Darja" of a Mother. Takes a strong mind to handle that!
Like it or not, AvNeil's relationship has evolved. Phase one was that young love, that matured into something very serious and real. Now it's that "Forever" love that even being apart has not been able to extinguish! It's easy to love someone who is in front of you, but not so much someone who isn! If you do, then that's true love. Neither Avni nor Neil has moved on and they never will! That is the next phase of the story.
