Sai's nature in impulsive and straightforwardness... and here her age and the way she brought up plays major role.... she is mufat as kaku says...
Sai and Virat charectors are so interlinked that we have bring other person somewhere or the other while talking about one.
She is broughtup by single parent and also have no relatives. She has independence to talk or do anything as she wishes. But she is brought with very good ethics and moral values. Practically, it doesn't matter how correct we are, there way to talk and behave in joint families. Children are not given much freedom of speech there. They have to follow some rules and behave in a particular way. They can't talk as they wish like in nuclear families where children can express their opinions and feelings freely. This is how Virat brought up. Never go against elders and always follow rules in general. When Sai entered the house, she faced rejection. She has to listen so many taunts and insults. So to overcome all those and survive in such environment where you are suppressed in each and everything, you have raise voice for yourself (all joint families will not be like that) which she did and also have to do. She did gave answers back and also she was rude when they were rude to her. She always has to interfere in each and everything and jumps into everything without thinking the danger involved in it( like amay scenario or running from vehicle like in precap) or repercussions of it like forcing her abha's senior to give his retirement without his father's knowledge or cancelling Virat's transfer... her intentions are always good but they can backfire also and can lead to big damage... for example if person in Virat place is not good person.... as once Virat said she can be jailed also.... or DIG sir also can do samething.... she was lucky here.. both were good and supportive to her....
Even though other person is rude and or not listening to her... she has use such words or say in certain way so that her saying stands out and other person will shut up instead of being rude... she doesn't need to give back always... sometimes she need to backoff instead of answering.... there is no use to say something to someone who is not even ready to listen to us.... she needs to put her battles wisely.... this is what Virat was telling her in early days of marriage.. she needs to change her way of speaking to Chavan's.... she is changed now compared to earlier days... she is tired down and dealing Chavan's wisely for example the scenes after her college function... Green dress...
When it comes to Virat..she can question him regarding his stance towards marriage and regarding Pakhi but sometimes in her anger and to hurt him... she speaks too much and insults his charector... like after amay scenario, she told he nothing when compared to her abha's toe nail, or him showing partiality in his duty, or recently also she demeaned him by telling he nothing infront of abha or something like that... I don't remember properly.... Virat might have behaved harshly sometimes and hurt her.... in all those times he treated her as his wife or partner and not as his responsibility which he taken because of his promise given to her father.... but as a person he is man of ethics and values and doesn't cross limits...... such words she used or wrong and she did not apologise till now... and also she has Said so many harsh words and cursed him during her father's death thinking he is reason.... she also did not apologise for that....
As many said... Sai also do mistake and use harsh words to hurt him but Virat does bigger mistakes where her Mistakes seen small..... so everyone neglects her mistake infront of his.... but she has to apologise for her mistakes even though bigger mistake is committed by other.... we don't even whether she realised her mistakes or not till now ot she neglected them... but I guess as she grows she will become better person ans learn from others...
If we observe, from compared to earlier days of marriage... Sai has toned down and Virat has started speaking or being firm when compared to earlier. They are on the way to bring balance between them.... He always spoke whatever may be when the situation comes that he may lose Sai or major thing regarding Sai... like her admission, ladakh track, ousting track, stopping Sai from leaving (here, he shut up up entire Chavan clan with single ✋).... from here Chavan's are always careful are doesn't taunt Sai infront of Virat... Ruby pendant and Saree scenario, Pakhi parents anniversary etc., he gave them back and took upon him and cleared his stance.... on Sai’s birthday he even tauned Pakhi infront of Chavan's. When he is normal and when it comes to Sai he will not back off. But as soon as he is hurt and angry... he doesn’t concentrate on anyone ot anything... only on his pain and hurt and acknowledged only words which are in his support at that time..... ofcourse Pakhi always uses this as her advantage to instigate everyone more.... he would gave reacted same way in all those instances even though it is not Pakhi and some other person using same words..... pakhi doesn't make any difference to him... but only and only Sai matters to him and his reactions will be based only on her actions.... like Sai's reactions will be based mostly Virat's actions.....
Regarding Vaada.... during that vaada track, when Virat is ready to speak she was not ready to listen and when she was ready to listen he was not ready to talk.... and as Vaada being USP of show..they will not clear it that easily or never clear completely 9n order to use in future to create new track......😆.. here Sai being mufat never asked him bluntly about Vaada and about his past... she should not let go of it when he is serving jilebis.. she should ask him to clarify clearly..... when comes to Virat, he is fearing that Sai will hurt more or misunderstand him more if he says everything clearly like in cafe incident, je doesn't want to hurt Sai by saying that Pakhi is still obsessed oh him.. it will be very uncomfortable to her to know that thing and he not even sure how she will react... he is fearing that the situation will become more worse... but what he is not realising is that the damage is already done....
Sorry I started with Sai and also went to Virat....
