Sorry to be dampner, but nothing will happen tonite. When it comes to being a prude the channel/ CV / scriptwriter are always consistent with Mann's and Geet's characters.
They like to mess up only when it comes to Mann's characteristics. What was that at the Manali Market episode yesterday. CAN Mann ever lose Geet in crowd like that after holding her hand and striding off with her so purposefully. PUHLEASE. Don't make the MANN look like an idiot in every other episode. He is the reason we watch the show.
Nothing will happen tonite or on any other night. They will not show anything that even has a whiff of "premarital sex".
It will be a Thanda episode with a predictable "we are stuck in highway cottage scene" and Mann will just cover her up in his shirt or something as lame as that.
Beside she is supposedly pregnant so Indian women don't have sex when they are on their to motherhood… not on Indian TV anyway.
Don't expect anything and you will not be disappointed. That is the way I am approaching the show now… else it is tough through the day not to get angry with the idiots handling the show at how they are ruining it.
