After watching the last episode (10th Jan 2013) I am sure that Anamika practices hypnosis on Jeet. Till now I had the opinion that he is just attracted towards her and therefore follows her instructions.
1. "...aapne ek baat note ki hai? Aap jo bhi kehti hain, main hamesha wahi karta hoon, kabhi koi sawaal nahi karta" (Have you noticed one thing? Whatever you say I do that without asking any questions)
First hint is clearly given by the CVs when Jeet himself remarks how he always does whatever Anamika instructs him to do, without any ifs or buts.
2. "...aur main kitna bada idiot hoon; aapko ghar le bhi aaya." (And what an idiot I am to bring you back home)
Then the scene in the previous episode (9th Jan) where he suggests taking her to a doctor and then just quietly changes his mind, taking her straight home. He even wonders why he did that in the 10th Jan episode...
3. "...aap apne aap kar lee kiye." (Please do it yourself)
Another clear instance is when he suggested wiping the blood off her lips. Anamika backs off and looks wickedly at him - moving her head as if she's controlling and directing him.
He mumbles like a robot that it'd be better if she did it herself. This is followed by him handing over the napkin to her and silently walking away.
Till now the hypnosis has been restricted and whatever Jeet has been made to do, none of it was of any threat to anyone. But in the future...no one knows...we all saw her evil streak in the last episode!
Also when Anamika learns of what Saluja's family is cooking, she may hypnotise him to say NO to Rano (not that we're complaining! This would actually benefit Jeet and the viewers 😆).
