Actually I would disagree with it...
Salman if anything was and is always Sana’s well wished...It was channel that wanted to exaggerate and elaborate these things.. That day Salman gave Sid a clear hint how things are coming out so decide which way you wanna go... Siddharth went Shehnaazs way..
Salman had a talk with Siddharth to back off if he doesn’t feel the same for her as in don’t lead her on.. That’s a different thing that we were presented everything in different way..SK knew everything that’s why he even himself confessed he was protective about Shehnaaz and doesn’t want her to get hurt..
I personally thought that this information was revealed to Sid because the creatives somehow wanted Sid to hurry towards a confession. Or if not, create drama by backing off. A gamble which would pay off either way. He was organically moving but after this he dug his heels in. He didn't give the creatives what they wanted but also didn't back off. It was evident that Sid then recalculated and changed his tactics i.e. became more conscious.
I sometimes wonder if Sid consciously kept messing up the creatives just for kicks as well. Because he would do exactly the opposite of what was the natural flow of BB e.g ignore Rashmi and align with Arti, bring Asim and Sana under his fold when the creatives wanted them to form other alliances, nominating Paras when creative wanted to save him, saving Paras when creatives wanted him out etc. He didn't play with the contestants but with the creatives. A meta game of sorts.
