This is completely my perception of how i tried to read their body language & reactions.
It is interesting that it was Bajaj who nodded at Anu and asked to spare him a minute, though their convo reflected the opposite. And it was visible that they both are putting a facade in front of the other. Anu knows that Bajaj sees him as a money-minded person who used & threw Pre and throughout the convo he was trying to maintain that facade in front of Bajaj. 'Aap jaante hein ki mein Prerna ke saath kuch bhi kar saktha hoon' was part of putting up that facade. While in between he was even trying to convey to Bajaj that there is a threat over Pre (in the form of Komo) and so to take Pre away from Kolkata.
While what Bajaj did was just playing along with Anu to make him believe that Bajaj doesn't know who is the actual culprit. With the way he was warning Komo & getting furious with Komo, while being extremely cool & giving a brotherly vibe with Anu is enough to understand that Bajaj knows Komo is the reason behind what all Anu did to Pre. What probably Bajaj doesn't know is that whatever Anu did, was a letting Pre go off from him forever act to keep her safe & away from Komo. He might be believing that just like it happened in the first Komo track, Anu was forced by Komo to accept her to save Basu's property & business. Which takes me back to two dialogs of Bajaj in his first track - Keep observing your target; then when the right time comes 'Go for the Kill' and 'You are a Lazy boy Mr. Basu'. Yes, that is how Bajaj exploited that weak moment of Anu (Laziness according to Bajaj) to 'kill' the AnuPre bond, so that he could 'take over' Prerna. And with him now accompanying Pre to BB and in his own word, seeing Prerna to be 'calm, composed and cool' he has confirmed that the current Prerna is not Anu's Pre whom he took over 8yrs back; instead she is his bold & revengeful Prerna whom he moulded into to be in these 8yrs. And it is with that confidence he told Anu 'I wished I could assure you that everything will be fine. But it's not going to be. And I will not regret for anything that is going to happen with you'. But, what Bajaj hasn't understood or maybe purposely have turned a blind eye to, is that evenif it is full of hate/revenge, Pre's heart subconsciously still beats & yearns for Anu. We got to see it today, when Pre lost control of herself for a second and that too not once but twice. And one dialog she said today was very significant. 'Mera Anurag tho mere liye kuch bhi karne ke liye tayyar tha'. And that gives the hint on how she is going to react when the truth unfolds in front of her.
So All The Best to Prerna. Because with the current track happening she needs it the most....Since, it is about How Pre is going to bring down KoMoNi to her knees and Whom she is going to choose at the end of the track - The Lazy Boy or The Oversmart Bajaj. ๐
