I don't think naman and karishma are wrong in the way they are acting. Namans not reacting yet but he somewhat does feel neglected after he's worked hard for these 10 years all of a sudden Naitiks back and RB 🤢 is handing over all the responsibility back to naitik and moreover giving him authority over naman. I don't blame naman if he's irked, yet he's being real mature about it (well for now) and he hasn't said anything much. Coming to Karishma I don't blame her either; didn't feel like shes wrong because she's used to running things her way. And she's reacting as a mother when it comes to Mishti and Naira..
But again devyani is to be blamed for that. Earlier she used to compare akshara & Karishma too. It was so annoying like why can't she just knock it in her head that they're too different individuals raised completely differently with different priorities and natures & to have the same expectations from karishma as she has from akshara is plain dumbness. And now she's doing the same thing with Mishti and Naira.. Yes Mishti is not exactly the perfect child but by saying you're acting like Mishti to Naira when she's fussing is obviously offensive to Karishma.. Her outburst then was quite justified too!
Well yes Karishma is wrong in trying to put her feelings in mishti's head too.. But I'm glad akshara made her understand and she did understand aswell. That was nice to see!! But I do think they should do something about Mishti and her "help" it's cute at first but imagine living with a kid who constantly wrecks everything you do and ruins your prized possessions.. Naira's reactions were justified..
