Everyone is so excited (in a good and a bad way) about what's happening in the show. But it's nothing but one of Bajaj's plan.
This is his attempt to whitewash his character in front of Prerna so she doesn't believe what Anurag will show her as proof. He's attempting to kill Anurag and does it in front of Moloy on purpose to pull him out of his wheelchair which will happen. And he can take all credit about bringing 'Prerna's Kaka-Babu' back on his feet.
This is just his attempt to divert everyone's attention from accusing Anurag to kill him and in fact, make him a better man in Prerna's eyes.
Same wine, new bottle!
