In yesterday's (22 november) episode, Sana said to Himanshi "Tod doongi tujhe, hai kya cheez? Khurana. Saaliye jatta naal pange...(some bit muted by Bigg Boss).".
(Saaliye jatta naal pange: Saali jatton ke saath pange). She was basically taunting her that she shouldn't take panga with her as Sana is a jatt and Himanshi is Khurana.
For those who don't know the reference, Shehnaz is a "jatt" and Himanshi is an "arora". I have seen a lot of this casteist nonsense both online and in person where "jatts" (only some ignorant ones) trying to portray some superiority over "aroras" (also called "bhapa" by some "jatts").
I thought this was really in bad taste by both Sana and Bigg Boss broadcasting it. Not only did they broadcast it but they didn't take any action on Sana while they claim and casteist, religious and other such conversations are not allowed in the house.
I always found Shehnaz entertaining in the show, but this has really changed my opinion on her. I have zero respect for casteist bigots.
