Dhiraj is the intended groom-to-be of Padma in "Road to India".
But after Brian travels to India to meet her after falling for her voice on a tech support hotline, she breaks off the engagement to her father's displeasure, as he had already paid for the wedding, so Brian offers to cover the costs despite being broke.
Despairing of getting enough funds, Stewie gives Brian the idea of going on a game show to make the money, but he immediately bombs by not knowing India or its culture. Apologizing to her, she reveals that her father give her younger sister to Dhiraj, but his failure on the game show convinces her to dump him.
