[UPDATE]
Okay, so looking at some of the responses I want to stress that I do not think that Khushboo should perform with an injury I just think that they should have found some way to put Khushboo in this episode. This is because her not performing becomes an advantage for her (because even if she does not perform she automatically makes it into the Top 8 since we all know that she is the only one in Amrita's group and if the votes are actually based upon the public then they will veto her elimination if she gets out. It also becomes a disadvantage for her because she does not get to perform so she won't get as many votes. That is why I am saying that they should have some way for her to perform this week.
