Until the end of season 6, Raj was extremely shy when it comes to dealing with women; he was unable to speak to them unless he drank alcohol. Raj communicates with his parents, Dr. V. M. Koothrappali and Mrs. Koothrappali, in India through a webcam. Raj is often seen wearing a layered combination of two shirts and khakis with a jacket over them.
