cvs logic and sid behavior

Could anyone help me in understanding the logic behind SIDS behavior. In yesterday's episode he said due to naagins hypnotism he could not recognise his roli okay I accept that as an excuse n forgive siddhant. He was saying he did not need eyes to recognise his roli only ehsaas is enough.but my question is why the hell he accepted that naagin as roli in first place when he saw that naagin for the first time in hospital. What happened to his ehsaas at the time. I also wanted to knw who the stupid /dumb script writer of ssk is? Few days before there was a scene where siddhant looking at the portrait n saying Rosid is incomplete without each other and siddhant could feel that roli is nearby n nothing happened to her if anything happened to roli siddhants heart beat would have stopped. But his heart could not recognise who the real roli is. How dumb siddhants dialogue or I could say how dumb ask writers are?

😡😡 agree I did not watching full episode but I always read Wu and after read I was so upset with him.how dumb and stupid his logic became .i think he even don't realized when he talk its stupid.i was expecting him to feel guilty and Begg forgiveness from roli.but surprised nothing like that.
