I honestly didn't find the confrontation appropriate wrt real life.
In India relation specially with In laws of a girl is fragile and we have to maintain the dignity for lifetime because it's about girl's entire life. And by dignity I mean both sides.
And one thing is about respect for elders, we have seen Sarla making fuss out of anything every now and then but she does all that to be center of attraction and get everything done by her respective samdhi's.
It's her trick nothing else.
But we have never seen her disrespecting the elders of the family and that's how it works. Sarla is smart enough to bully Ishqi and Sonu bt she has always respected Dadi and never said a word to chacha/chachhi.
She doesn't find her authority to question anything to Ahaanas as well.
Our family never let us speak in such matters and whenever we try to do they sushhh us by saying 'Bade ke maamle me chote nhi bolte'.
I agree sometimes our elders are very wrong and they need to understand and look from our perspective but this was not the time.
We have seen Kartik poking his nose in many matters but they family shuts him up cuz of the same reason although he always had valid points.
And the thing about Sarla is that she's a sort of personality whom you can't win by pushing her on back front which Ishqi was trying to do. She's a sort of personality that can go on back front if something out of her expectations is done, example she's trying to create a drama and someone meddles in between and give her the lollypop which she wasn't expecting. To make her head bow down once AVM said sorry to her on Jagrata, she was wrong there but she felt little in front of AVM's big gesture to save Sonu's marriage. That's how you sush her. I'm not saying today something similar was required but for Ishqi (would be DIL) to say 'Ho gaya apka drama ya aur krna hai'? Was way over the top.
DIL doesn't have much say in these matters because first Sarla is elder to her, second she's outsider as of yet, she just can't make her point by shouting at her and passing sarcastic comments about her lifestyle on such a big matter. This thing has to be handled maturely and this is not the way Sarla or anyone from in laws can be shut up.
In real life this scenario could've been very disrespectful for both the families where would be DIL was kind of shouting and making fun of her nanand's Saasu ma.
In my honest opinion a mature conversation was what needed to stop Sarla.
Like someone pointed in the EDT, Raj was noway gonna support Sarla in this, she's nobody to take the decision of breaking marriage as it solely depends on the couple.
Also, it's not just for today it's for every typical day where Sarla tries to do something like this. It wasn't her first time and for Ishqi it would've been sober to stand in the crowd and let someone else handle this. Probably Raj, Ahaan or anyone.
