Which is why he switched gears...his mind racing to find ways to distract her...like you distract a little kid with shiny things...and at the same time keep up the pretense of the game as well...the only language he feels safe communicating with her at this point...it's either games or try and kiss her...Holi pe bhi toh yehi kar raha tha...lol
I really felt for Nandu in that scene...bechaari totally got played by him...so innocent she is really...lol...although by the end as she gave him a lingering look before walking away...that was an interesting enigmatic smile...
Honestly these two will always keep on playing their games...lol
