I don’t agree with any of your points..because they lack logic and sound extra Filmy..
She doesn’t seem to be outright negative and neither outright positive... actually no one in the house is.. lets get that straight... they don’t look like criminals with a terrible history... so we cant say they are playing a dirty game or they are a pure soul....
Secondly, this is a game.. so everyone wants to win but to survive for long they definitely need an emotional support. This is with each and every person.. some need a person to talk to whenever they feel like... like sid.. he needs his personal space but he also wants to talk when he wants to.... like mahira ... the game thing is all new for her so she needs one constant support and buddy and thats paras... asim needs someone who can joke with him.. have a conversation with him on how to move ahead in the game .... like that even Sana sees the support in Siddharth .. partially for emotional and could be partially for staying and moving in the game...
However she’s a bit different and her journey is unique because we haven’t seen such a person in bigg boss..
My analysis is that Sana definitely got attached to Siddharth because he is very straightforward and can tell on the face what he feels. So for one i get that sana is a person who trusts people who can tell her on the face whatever they feel.. the thing that she keeps talking about ... vibe... that sort of gives her a sense and she mainly relies on that...while others rely on people who are just good to them...
To conclude, Sana is with Sid and Sid is with Sana.. Asim is with Rashmi.. Rashmi is with Asim..Mahira is with Paras..Paras is with Mahira..Aarti is with Sid..Sid is with Aarti..etc.. keep making these combinations.. in the end they are all players here to win who need a person to talk to and also support them in their game.
