I think with the grand and incredible twist, coming full circle to the Bajaj we had hoped and dreamed of, a lot in their panic are forgetting that the episode started and established the very genuineness of Bajaj's character. Him wanting to comfort Prerna, his internal monologue about her being upset but still loving his daughter and fighting for their family unit through it all, his soft gazes, his genuine smiles. When he sat and watched his wife and daughter, who's benefit was that for? No one's. It was him, all aching and yearning and wretched for love part of him. There was so much genuine stirring of the heart that it pulled at you, it rushed you forward to Rishabh and it made his subsequent dialogue of not letting anyone get between his family, even more impactful.
But the switch, the flip, the face of the coin he keeps hidden, the reveal was masterful. The dialogues Anurag was uttering were near nonsensical before Rishabh snapped into Bajaj. Anurag was stuck on she was mine, my person, you stole her from me, you took her from me, she is mine. To Anurag, Prerna is no longer someone he loves, it's someone he had. A possession. Someone who belonged to him, and now no longer does. And like a toddler who's favourite toy was ripped from his hands, he's acting out. And Rishabh knows this and since he anticipated the turn of events Anurag thought he had solely under his control, Rishabh drops his facade so quick. He's not playing around with the young Basu, no, he's telling Anurag just how he's winning and how he plans to win. BUT a lot of Rishabh's movements were exaggerated today. His over the top show of annoyance, his willingness to admit that he wanted Anurag to die by his hands, his irritation at Anurag's soulmate jaap, all of it
When Rishabh admits that there's no way he could ever let Anurag take Prerna away from him, it wasn't a moment where he comes off as unhinged, that was incredibly deliberate. My wife has become important to me, my wife is important to me but my wife has someone else in her heart and I have to erase that person from her heart and to do that, I must erase that person's existence. Rishabh Bajaj knows, is aware, has shown us, that if he TRULY wanted he could get rid of Anurag without a trace. That it would never come back to him even if the Basu tongues blamed him. We know what he is capable of now. But that dialogue? It seemed way too obvious. Way too in your face Anurag, for me to believe that Rishabh actually meant it. Rishabh was emphasizing, over and over, that he had warned Anurag. That he had warned him and the boy still wanted to play with fire, which is a direct full circle to Rishabh's earlier dialogue about protecting his family. Anurag is, a threat, to the stability that Bajaj now has in his family.
The thing is, we have never since the beginning, seen Rishabh this animated. This overzealous to make a point, this unhinged, this unraveled. So I actually can't help but believe that it was all very deliberate, because we know as soon as Prerna enters that scene, his switch will flip. There were small ticks though, the way his hands shook as he tried to explain to Anurag how badly he'd behaved, as he rubbed his thumb against his bottom lip, the way he held his cigar. The way he said oh I'm so sorry, what were we talking about? oh yes the cop - that was something else entirely. You mean to tell me that Rishabh Bajaj, even for a moment, a man who thinks about everything five steps ahead, forgot his train of thought? I know we could argue that this is all pent up frustration that came undone, but I think it was extremely purposeful. He's becoming the villain for Anurag, because that's what Anurag believes him to be. I don't doubt his words entirely, I do think there was truth to what he was saying, to everything he was saying. I do believe he caused the accident deliberately, I do believe he tried to teach Anurag a lesson.
But it's the way he was saying it that seemed so purposefully done. Rishabh isn't one for dramatics or theatrics, and we saw the slow change in demeanour when he said he would protect his family. But the Bajaj before Anurag seemed to be an over-animated version of the man we know well. The fast movements, the fast-paced talking, the quick, nervous ticks of his hands. But Rishabh knows how Anurag's mind works, and he gave just the right amount of fuel to get Anurag's mind off of the present and into the past. Anurag will be stuck in the past of Bajaj's life, as Rishabh moves forward with a grander play up his sleeve. Just brilliant 
Rishabh gave Anurag exactly what Anurag wanted, a villain. But the hunter gave the hunted, just the right amount of information to get the prey stuck in a loop of the hunter's choosing, one that will occupy Anurag until Komolika enters the scene, which will also be Rishabh's doing.
And then the precap? Where he says he's never revealed that many secrets about himself before, a direct come back to his dialogue that he only reveals that which he wants others to know of him, that he only let's those come close to him, that he wants. He was provoking Anurag, pushing him to react to his reactions. And then we see Rishabh again with the part of precap we've seen before, where he is more like the Rishabh we know. Careful, constrained, each word chosen for maximum impact, but not at all the unhinged version of him before Anurag today.
The one thing we know of this man is everything he chooses to do is deliberate. He's been provoked and thought a fool of, but he proved Anurag wrong today. Nothing happens, unless Rishabh deems it so. They may all be in a tangled web, but it's one of his making.
The question isn't which version of him is real: Is Rishabh the illusion or is Bajaj? The answer will always be he's both. He carries darkness well, it's in his bones. But his smiles are real, his heart is real, and the changing turn of the tides inside his heart are real. But the unhinged man he becomes to protect the wife and daughter he cares for, in the only way he knows how, is just as genuine as the man who watched them fall asleep softly.
