I wrote this in another thread and writing it here, the latest scenarios floating around about Mishti killing Juhi make sense. Mishti in the past said she would protect her angel, she can't take anyone hurting her and I am sure she will witness something between Juhi and Avni that forces her to take a drastic step. Avni being the person she is will take the fall because she does not want Mishti to be another version of her. Lets face it despite the fact Mishti is not Neil's daughter it does not change the fact Avni sees herself in this little girl, Avni's past still haunts her and she will do whatever it takes to ensure no one lives through what she has. I think this is where Avni and Neil will clash, it won't be a case of not believing her it will be a case of not being able to understand Avni. Remember during the RM track when Avni was willing to be killed? Neil was so angry and hurt that Avni did not think about him, it was only about her past, her pain and it was upsetting for him. I can see history repeating where Neil feels he has no importance in Avni's life, that she is willing to let her past affect her present and choose to pay the price she did not commit. It would fit with who Neil and Avni are as characters and the dialogues in the promo. Neil wanted his love to overpower the demons within Avni, he will feel that was defeated.
I am really hoping something like this happens because one of the major concerns by fans is the fear Neil and Avni will be destroyed and we don't want that. This scenario looks more fitting since Avni's past haunts her so much, she is unable to escape those scars and Neil will believe he has been unable to heal her. There will be no divorce but a separation, leap happens they meet again and angst, tashan ensues but with a twist these two still love each other deeply. It will be interesting to see how CVs handle this track since there is still the fact Vidyut is around and he won't make life easy for them but he may back off thinking he has won by creating a rift. There is a lot of potential for this upcoming track if executed right, the most important is keeping the characters of Avni and Neil intact.
