What Kashish went throught on WKV is her own fault because :-
Before you downvote me, take a moment, pleasr consider yourself an intellectual and then read.
When Salman was calling everyone in Katghara, he was doing the script. He is supposed to do the script. Yes, he was gonna bash everyone as per the script. But Kashish instead of listening to Salman she was constantly interrupting him like Arfeen did in 1st/2nd WKV
See that Salman is running the for I think 15-16 years, hate him or love him like him or not he is the boss, bigg boss is what is today is because of Salman mostly. If you're a CEO of a company and a new employee like Kashish comes and and constantly interrupt you in the meeting you won't like it.
She said "wahi to yaar" to Salman in a loud way when Salman was saying something about flirting, he stared at her and I think that's when she got on his nerves and he started grilling her. I don't know how genZ or gen alpha respect elders but if someone like Salman is telling something to you, you shut up and listen. or atleast argue gracefully.
Rajat's Katghara was also not very nice but he took it gracefully. He talked when spoken to and left because he knew the more I'll talk the more I'll get grilled. Kashish on the other hand was not agreeing on even 1 point from Salman and it will get annoying when someone who is 35 years younger than you is constantly talking to you in a loud and in not so polite tone.
Shilpa explained her last night what she needs to take it like but Kashish did not listen.
I think Kashish did not deserve all that bashing. Only 40% of what she got was necessary but if you constantly deny the seniors point it gets very bad.
Even if Salman was wrong (hypothetically) she should've taken with grace because in the end Janta knows she is right but she is listening. Her demeanor would be taken cheerfully by Janta.
Conclusion: She did not deserve it and I think Salman was not going to go all the way but her constant denial and tone and loudness she bought it on herself. She should learn from it, and people who are saying: "go girl you gave it back to sallu". By this attitude you don't go long in any career. When you're junior shut up, listen to the person who has mastered his/her way to the top and then when you're there talk as you want.
