I always admired Zariwala as I thought she is very mature and is sorted mentally. Seemed to make reasonable arguments and also seemed loyal.
Since Himanshi went, Zariwala has just been ruthless with plotting and picking fights. Specially with Asim. What happened with the Bhau ka letter, I totally understand, she was already agitated and she didn't think once before shredding it. Asim did make a valid point, but calling her a rat was once step far.
However, with the way she has been back bitching about Asim ever since is totally uncalled for. As Asim, as far as talking about Shefali Zariwala, he doesn't do that behind her back at all.
Not only did Zariwala instigate the toilet duty incident, by telling everyone that Asim did do all hsi duties under Himanshi's captaincy, while conveniently leaving the part about why he had to do all the duties-because of Zariwala's unfair decision to make Himanshi the captain, which followed all the housemates boycotting work. This is the reason Asim was forced to do all duties.
Not only this, in the photo task recently, Paras repeatedly kept saying why don't we have Asim and Sid for the iconic moment, Zariwala showed her true colours by saying -"usko itna importance kyun dena hai? Mere saath chup chaap gym waala pose kaafi hai uske liye"
I mean seriously? Who is this woman and what did she do with Shefali Zariwala?
So much negativity within her! Not expected from her. I thought she had class, this was just cheap.
