She is treating herselflike a normal contestant who needs immunity. Why didn't Srishty say anything to Dipika on her face that, why does Dipika not deserve to be the strongest, she did not say that, but did backbiting with Karanvir how Dipika is shaatir and took advantage of Karanvir nominating himself.
If Srishty is that blunt and honest, why did she not say that, Dipika does not deserve to receive immunity, it is very easy for her to say in a group, but not infront of the person you have a problem with. She still acts cordial with her, but has insecurity deep down and enjoys when someone is speaking against her.
Dipika was not guilty when Sreesanth came, but she was just nervous how will he react because Anup Ji already said how he is upset with Dipika and Shivashish for voting him out, so she felt reluctant in approaching him.
If I was in Dipika's place, I would have also cried because she took care of him for 4 weeks and if this is what you get after being so kind, then anyone would feel broken.Sreesanth refused to acknowledge her properly and was alright with everyone and isn't that disrespecting a woman, he is a hypocrite who never respects anyone.
