BajRag was fire, legit fire. Anurag was composed, held his ground, concise & in control of himself. Anurag could see through Bajaj a bit in his first meeting. With one meet, he knew what this man exactly was. That's why he warned everyone about him rightly. It was practical & looked real. That's how enemies are confronted in business world.
PreJaj was meehh. She was exact opposite of what Anurag was. I know women are emotional but come on now. We have seen Prerna in Komo track. She used to be composed & in control of herself against smug faced Komo. With Bajaj, she was an open book of weakness despite being warned repeatedly, that Bajaj cunningly used for his own advantage. Prerna should have stopped herself when Bajaj warned her for the first time. That's the first clue to be careful. Either Prerna is being deliberately dumb here to not see the kind of man Bajaj is or she doesn't want to see. Bajaj isn't Anu, Mohini or even Komo. He doesn't lose his cool even under stress, his actual power is in his ability to listen to other side & keep silent unless he needs to speak. One look at him is enough to catch a glimpse of his shadyness.
As for Bajaj, he is shady but he has his own compromised morals. He could have agreed to Ronit but he didn't. He actually waited to have response to his proposal even when Prerna said NO on his face. He was honest about Ronit to Prerna. He even delayed making a public announcement of taking over Basus until Prerna's response is final. He knows that Ronit is desperate for his help & so is Prerna. He didn't cause this situation but he is using it for his advantage. He would wait for Prerna to agree to his proposal, then he will agree to Ronit's proposal & take him into confidence. And that's how Ronit's truth will be out & Anu will be out of jail. It's a different story that Ronit would manage to escape to Switzerland. Bajaj doesn't want to save Ronit, infact he doesn't care about him, he too wants him in jail but on his own conditions. The shady part here is Bajaj delaying Ronit's arrest unless he achieves his goal of destroying Anu completely.
