100% true. Main problem with Upen and Karishma is they never accept their mistakes and others should not make jokes on them. On top of that they think they are only good human beings. They can make Ali sick by giving KaayamChuran in the name of fun. One time is fine but they mixed in Ali's food multiple times. That KaayamChuran part was not shown in episode otherwise people would have known how evil they are.
I can't forget Karishma's irritating face when she told "Yuck Ugly insaan" to Gautam in Yes/No task for a simple thing like Make up. They can talk so mean about others but Salman can't even joke???
Definitely she is trying to use Gauhar's card of going against Salman. I guess already some people started supporting her since yesterday. But Gauhar's arguments were right sometimes and Tanna's arguments are always baseless.
