A red-headed smoker at the time of the Kennedy assassination, Berenyi was also given to wearing exclamation points, perhaps indicating she knew of the Doctor's affinity for wearing question marks. Like the Doctor, she possessed a fairly detailed knowledge of Earth culture and history. She seemed well-versed in the pop culture of the 1980s and was known to like The Jesus and Mary Chain, Sonic Youth, Cherry 7UP and Arthur Miller's biography.
