I get the feeling that they are going to be showing the Lonavla type of tabela wala scene real soon.
First they'll try to show romantic scenes in the bus where they'll show Katie using Devinder's shoulder to sleep on and later when she shows attitude to him he will (like Aamir Khan in Dil hai ke manta nahin) whole night you had no problem using my shoulder as a pillow and then they'll start their argument over it.
Then, perhaps the bus will break down and these two will have to find a place to stay and will land up in some tabela like Dev and Kajjal did in Lonavla. Then these two will try to connect by talking about their different worlds and dream and then.......
