Sana is actually fed up of Sid.
She thought he has something genuine or rather he will dance according to his tunes. Let me put it more nicely, a man who will pamper her in own words.
But what Sana really needs which she is unable to spit it out unlike Asim is SELF RESPECT
Madam knows that Sidnaaz was also one of the key factors in the show. Now Sid is showing more concern towards Mahira and Aarti Abdullah is telling her 1.5 bacha hai, Sid point blanks voices out his opinion that once you are not in the house then I'll romance with AAarti
Sana has gone full circle with all house mates the only angle which was not tried is dost bane dushman with Sid
Around 1 mnth is remaining, Sana next story line is war against Shukla
