Nice post! I meant to make one about the confrontation but you have done it already so I can just put my comments here now.
First of all I think TTS brought Pintu to the police station on purpose. I think it was all part of his plan to have his son see how much he was helping the family so that later if any problem came up, he would be able to use this in argument. He may have even predicted that Vidya would lash out like this and Pintu would come to his rescue. So it was a win-win for TTS. I gotta give it to his planning. He has managed to completely strip Krishna of all her support, first Babloo, then Vidyapati and now Pintu so he must be feeling mighty good about himself.
How petty can he get?
I feel like Pintu is stuck in a tug-o-war between Babloo and TTS who are each trying to make sure he turns out "right". Unfortunately, TTS' influence is much stronger which is where Pintu gets that sense of entitlement to do whatever he wants, even if it breaks rules (the chaat thing) and that whole dadagiri attitude. On the other hand, he also has a big, soft heart and an instinct to help people which Babloo tries to cultivate, along with grounding him every now and then, like when he makes him ride in the tempo. Pintu at this point is unable to decide where he belongs but sort of goes with the flow of which ever person he is with. In Babloo's absence, it is natural that he be completely and even blindly loyal to TTS and adopts some of his behaviour, hence the hateful speech about class difference.
What he did not see coming was Krishna!
She knocks all that TTS-induced gas right out of him and although he won't be able to see that she is right just yet, he is surely affected by her words. I think more than anything he sees this timid padaku, with whom his association so far has been one where he has had the upper hand and been telling her what to do. All of a sudden she flares up, tells him she doesn't need him and kicks him out. The TTS inside him is angry and his ego is severely bruised, but somewhere deep inside he feels that remorse for the crass way he insulted Vidya on seeing Krishna's own dignified defense of her father. I loved Krishna's line, "ye humare papa hain" as though reminding Pintu that Vidya was not just his dad's employee but also the faultless father of children who would stand up for him and his integrity and should be treated as such.
To be honest, though I don't think anything romantic is brewing just yet. I think Pintu did have a little crush on Krishna because he is intrigued by how different she is from all the other girls he knows (Pinky and clones) and I think he also liked feeling like her saviour. But now she has shattered the second image and guys like Pintu don't take it well when their egos receive such a huge blow so I think he will be a bit disillusioned now for a while and might even convince himself that Pinky is a good idea. His crush on Krishna was encouraged by his bhabi's hints and how much Babloo loves her as a student but now that they are not there and Krishna has insulted him, he may lean towards TTS' way of thinking and try to accept Pinky, though Krishna has made a place in his conscience if not his heart and she will surely be pricking often.
Woah! Enjoy the essay.
