I dont know why in every conversation or argument it comes that Nikki is confirmed because she has proved herself 2 times and won the immunity.Well I think more than proving herself she has been lucky/seniors have been partial towards her.
First task Shehzaad had dropped only 2 glasses she could have played and won it but she went on to destroying without even saving hers.To conclude with Sid also gave real lame excuses to make her win instead of Jasmine who had her glasses full even when both had dropped.
Second Abhinav was forcefully pulled out of the tractor by seniors due to confusion and Nikki got to sit.That was like.................................. Gauhar going on to supporting her fully.The real winner would have been Pavithra and Abhinav if he would have not been taken out.
Both the times she won due to favourtism and not due to her great task proving skills.I think she is extremely smart and knows how to act in every situation.She won everytime because of her smartness and not cause of the task she has proved herself.
