The "ese na hoi ki bohat der hojaye" seemed significant. It seems like because they haven't talked about their feelings that Avni will be in doubt about how Neil feels when Juhi comes back and Neil will be in doubt about whether she wants to stay with him or not. They'll be treading on egg shells and feeling things without saying what they need to say because they don't know what the other wants or feels.
I think it'll all eventually come to a big climax where because of this doubt she'll think he wants Juhi and will try to remove herself but Neil will stop her and reassure her and I think that's how his "I love you" might come out. Kind of like her being like "I'm leaving you so you can be with Juhi" and him being like "But I love YOU Avni. Why don't you get that?"
Anyway that's what I think but I might be completely wrong but either way considering how confident Shweta feels on how Neil will be impacted by her Juhi plan I'm pretty confident that it'll flop completely. The more confident she feels, the harder she'll fall.
I also had to lol at the scene where she's like Avni will never make Neil happy and no one knows this better than me and its like is that how she justifies it? That she's doing it for Neil because girl is delusional. I mean in just this ep Neil looked so happy with Avni and just that scene where he goes to sleep with Avni. He looks so at peace with her so having Shweta say that crap in the same ep as those scenes shows how wrong she is. If only they could stay in their little bubble forever and stay away from mother dearest. The only thing destroying his happiness is Shweta. He'd be a lot happier without her in his life.
Also I've got to say that I love the precap. Because it shows Neil doing the pooja with Avni when DD said he doesn't do it and Shweta thought reminding him of Juhi would turn Neil against Avni. Seems Shweta doesn't know her own son
