My Thought

Yes he was angry with Avni but also promised to not anyone understanding her fear but showing her that what she is doing is wrong

This reminds me of neela when she support Neil in putting Avni in Jail... I agree Neil throught out said he was wrong but avni is badly scared since childhood loosing people first she lost Ayesha then Neela (in betwwen these two she also in a way Aman/Amol)

So she fear a loose of one relationship she she never got which she see in Prakash. Hance her fears are justified as mother it would have been the most hard task to keep away from your own kid the hate Neil is showing her has made her believe that if Neil is told

1. He will loose her son who doesn't know she is his mother to Neil

2. Her son might hate her

Now coming back to Prakash knowing Mowgli's truth

Yes he is the first Khanna to know the truth...

Prakash has always been given most importance in comparison to other side male characters on ITV show that make he will some how get to know about Neela's death before Neil

Not only the fact he unintentionally killed Neela who was saving Neil but he was reason Avni did what she did and hance both AvNeil suffered because of him and are still suffering because of him

If we see the Juhi track (I know not many liked it) to show Shweta change of heart they took a good amount of episodes now that they have a time fix (which is not conformed how long it is) they will surely show Prakash's guilt for a few episodes

Now coming to METALI

When ever it comes to girl except Avni Neil brain stops working be it Juhi or Metali that why he proposed in anger...

I remember in one Interview Sana said f the script is followed she will be positive' if this understood knowing NK CVs jo bolte hota nahi jo hota hai audience ko humesha aacha lagta nahi hai...If i am not Poonam also said she was positive lead

So I am saying like Juhi, Metali is going turn negative now that she sweta supports her even Neil has proposed she think she will get what she wants she will some how get to know Mowgli and about Prakash killing Neela and will hid it so that AvNeil don't come close by any how...

With mowgli and Neela truth Prakash will get forward Metali truth of her knowing and not telling anyone that she could get married to Neil holding Shweta responsible for everything her constant support for metali and her concern for Metali and not realizing Avni situation at all

And she can never love Avni like Neela and understand her...
