My subject of contention is not why Prachi is back but how she came back. Every reality show has wild card entry but JDJ based on internationa format didn't have any and suddenly just because Ekta Kapoor threatened channel and Mr.Basu, they brought in this new format and then again by just calling two names and ignoring all others is really an obvious biased decision.
It doesn't matter if it was Diwali so Gujarat was busy celebrating and not voting for Prachi. Since when is audience voting accurate? If one had decided to participate in the show then they should be prepared for ouster too. At least calling back all celebrities and then choosing one would have made it look authentic.
Having said that imo only two who deserve to be in final 2 are Sandhya and Prachi.
