Regarding the speculations - (he isnt faking but the mus)

Rana ji is definitely a gentleman..he had insulted gayatri only when he messes up his head with his ex wife and new wife gayatri ..as he wants to be alone with her memories but as gayatri is his wife ,so disturbance comes naturally from her..

1.he insulted her at suhagrat as he saw gayatri within sona's cloths
according to his thoughts ,I am pushed to get married with you now you are trying to fit in sons's cloths ..leave it ,her things are priceless for me ..

2 secondly he demeaned her on that dinning table with that sauda wala thing ..someone told him gayatri is part of his deal with this marriage ..he thinks that she wants only queeny tag

3.he dumped down to suffer ,blamed her as nachanewali ..for Mr Wilkinson ..
on this matter ,he thought if he is alive then why there was need for gayatri to beg onwards Mr Wilkinson.. he doesn't like his wife to beg onwards others for anything ..

His best quality is that he is so straight forward ..he accepts his mistakes and he immediately seeks apology too..he realised gayatri was about to loose life just becoz of him ..so he tried to save her at any cost ..he isn't back stabber ..he is do genuine .
Then what is the bad quality of rana? ..he believes on others blindly but never tries to think that he might have been misleaded ..

so I think ..his concern for gayatri is genuine.. he started to come close to her ..he started to feel for her..his feelings can't be fake at all..as mala gave him a reality check..and he repented thinking how selfish he was with his own sorrow of his lost love ..he said he hadn't seen his own people's tears ..in that people gayatri also comes ..

But then the conspiracy lies at the corners of rajmahal ..even that black veil lady is ready to spoil everything ..she heard the words of rajmata how she planned to shoot gayatri ..so I feel again he will think that gayatri was pretending of being ill person ..as that doctor was also a part of conspiracy ...so its natural to think rana that gayatri was doing ill drama..

regarding sid interview where he said ,misunderstaning might happen..

my conclusion is that he isn't faking but after getting misleaded he might feel cheated ..he will take his steps back which he was forwarding towards gayatri..

I would like to blame rajmata for it she did it all but from their marriage itself ,she always bring only conspiracy to bring new colors in her son's life..
now both rana ji and gayatri will break down..

I have a feeling that rana ji won't tell gayatri to leave as he genuinely started to love her ..but he will give cold shoulder to gayatri ..will start to maintain distance from her..as he is already started to like her ..he might confront her that he had started to like her
