What was point of Shreya's advantage

I read on internet that Harshad is gonna sacrifice his place for Shivangi after getting a chance to stay in finale but only one of them(Shivangi & Harshad). Then tohh Shreya's advantace is a waste.!!??.. Kya faydaa bhaiii jab wo jise eliminate krna chah rhi thi use kr hi nhi payi toh..!!

WTF IS WRONG WITH U MAKERS!!???... CLEARLY WE CAN SEE YOU'RE BIASED!
