It is none other than the Queen herself
Dipika.
Dipika did fantastically well. Both times when she faced Deepak.
Dipika has a strong voice and is very good at putting her points forward without any hesitancy.
She is a good lawyer because she provide examples when needed therefore she is able to prove her point.
Infact dipika is the best contestant at giving the best reasonings and this has been seen throughout the season.
For example on weekend ka vaar, Dipika is the one who is mostly asked to give her reasons on a particular situation. Why does salman ask her that? It because she can give the best logical reasons. Most contestants give daft reasons but she doesn't. Furthermore in bb, contestants can't speak over her which shows that she is so dominant.
When she raises her voice, it's very hard for a contestant to speak back at her and therefore they can't win against her.
These features mainly occur in the person who is a deserved winner.
She is this season's most strongest contestant.
