Ankur Nayyar as Samar Khanna
He is introduced in the show as a Special Intelligence Branch officer. The audience is kept in the dark about his actual identity -- he might be a cop, a thief, a mathematician, an art dealer, a con man, or whatever. He is extremely protective about Irawati, but there is a purpose behind this.
