Like the title suggested it was totally unexpected twist..
But what happened to the snake? Arnav locked it..but wasn't it strange that the snake didn't act even when Khushi shouted out to Arnav and all their conversation?
I too have Khushi's similar kind of phobia...and well, you did succeed in making me nervous wondering where did the hell Khushi disappear to..
While it was necessary for Arnav to realise his love for Khushi, and for Khushi to confess her love - the situation created for that realisation was quite dramatic according to me but you presented it well...that tension, anxiety, not knowing what happened, that fear, that emotion was brought out well..but snake could have been avoided (my suggestion) mainly because it made me nervous..otherwise fine..
I loved the setting you gave in the start - Land Rover - Porsche trip- it reminded me of picnic trips...But again why did Anya almost screamed before asking Suresh to stop the vehicle..I lost connection there..
Anya's thoughts were nice to read...Arnav's tension upon receiving Anya's call and his panic was beautifully done...
Oh Arnav-Khushi moment at the porsche rear end was nice..--that promise was sweet...
