I have a feeling that Neel did not do anything in there!
The show will see how audience react, and then let us knwo what really happened inside that room.
If people say this is bad, that Neel has come so low down...then, they will show as if, he didnt do anything inside and acted...and will change the story
If peopple accept, then they will show as if somethign did happen...and now Vaidehi is pregnant!
Maybe Pallavi didnt want to do any intimate scenes, taht is why they didnt show us much.
