@nilsa, it did not bother me either to see Neil referring to Mishti as his, like you said that is his belief right now and fans should really rest easy in knowing for a fact that is not true. It is not like Neil is going to be the dark forever, the truth will come out to him and Juhi will caught in her web of lies. Juhi teaming up with Vidyut is what is going to make things much worse for her character because no one will have any sympathy for her, she claimed to fear this man yet now in a desperate attempt to keep her lie from being exposed she is ready to team up with him. Neil is going to see Juhi was never what she appeared to be to him.
Interesting theory about Vidyut and Juhi but after watching this episode it became clear that Vidyut and Juhi were not in touch all these years. Vidyut being bitter towards her is the real deal, there is a reason he kept custody of Mishti and does not want her a part of Mishti's life but for now he will probably use her to get what he wants. Vidyut wants revenge which is why he is not taking Mishti back yet, he is a character who plans his next move very carefully and with Ragini in jail telling him what to do it is going to make for an interesting watch. Vidyut is obviously not going anywhere anytime soon so how will Neil take him down while protecting Avni? Will he be able to defeat him at all? Is a redemption track still possible for Vidyut?
Bang on about Avni, she had plenty of opportunities to walk away from her marriage but chose not to. I do not believe she would try and make a happy family with Neil, Juhi and Mishti while she sacrificing her marriage. Avni would not make the lives of anyone that miserable, I feel her walking away has to do with trying to distance herself from Mishti at least temporarily so she can form a bond with Juhi. Avni is more determined than ever because the plan was to send Mishti and Juhi away in seven days and that cannot happen if Mishti cannot trust Juhi. There is something else in the works here.
