Bobby and Abhisheik being the sons of Dharmendra and Amitabh respectively, are aptly given a shot where they replay the famous "Yeh Dosti" song as a tribute to Sholay.
During the scene where Abhishek is telling the story of him and Lara he mentions that she is a Pakistani and he met her in 1997 around the time when Princess Diana was in Paris, France. This was fifty years after an Independant India and Pakistan were created. In one scene with him Lara he says to himself "She will take revenge for the past 60 years" So he jumped ten years ahead.
