The lad in red is Vivek (Mohnish Behl), the oldest kid, who is a stepson to Mamta. His biological mother (Ramkishen's first wife) passed away when he was a baby. This guy is unnaturally shy in his own home.

Vivek is disabled in one arm due to a 'childhood accident' which could very well be fapping for extensive periods of time.

The lad in white is Vinod (Saif Ali Khan), the youngest son and a complete annoyance.

So anyway, the party has only begun. Guests start flowing in. First arrive Mamta's lawyer bro and his wife. I don't even know this dude's name, they just call him Vakil (lawyer) or Bhaiyya, and his wife Bhabhi.
