Yuvraj and Suhani will land at their honeymoon destination, and have nok-jhok about some silly thing. Has anyone noticed how Su's started doing nakhras since confession? The 'jao-hum-tumse-nahi-bolte' type, accompanied by turning away and crossing arms? This may end in a minor fight, or Yuvraj will go straight into loverboy mode, stepping close and holding her arm or shoulder, and talking her out of it. Small romantic moment may follow.
There will be maybe 1 or 2 shots of scenic beauty and both happy, with some teasing. Maybe a little hand holding and stuff. Then we'll get cute banter. Following this, there will be scene of RomRaj or RomComRaj making moves. Just as kuchh kuchh about to happen, a scream will break the moment. Sis Birla has got away from her minder(s) and made like a homing pigeon for Bro (maybe dadiamma arranged for this). Yuvraj will try and ignore, but Su will want to poke her nose in (or vice versa). End of honeymoon.
