If you have played the game "Where is Waldo?", you would be glad to know that I have found Waldo in this pic. The guy with blue shirt and a baseball cap (back to front) behind these three people is Waldo.
Sandeep looks so much like Anil Dhawan, from 70's. Farah looks out of place (kabab mein haddi) and so she decided to pretend that she was not there. Karan is trying to make a pass (aadat se majboor) and could not resist leaning on Sandeep. Sandeep responded well. The guy standing behind (in baseball cap) is looking at all this drama suspiciously.
