She craved her father's approval, but felt that he favored Dexter. When Dexter was 19, Harry fell seriously ill and gave Dexter "permission" to kill Mary, one of his nurses, who was intentionally poisoning him with morphine.

He fell for the female party planner and they were in a relationship until the end of season 3. He is also shown to be
