The four contestants were asked of the bottom 4 who should be out. 2 voted for Mika, 1 for Sonali and 1 for Prachi.
The four were
Sandhya
Jay
Ronit
Negi
I think it was Sandhya or Jay, but I could be completely wrong. I thought all would have voted for Mika, I even understand Sonali, but Prachi did not make sense. But I guess after seeing Sudha voted out, hoping for sense is a fallacy.
