Luke Francis Harris is the son of Dr. Alex Reid and was named after her late brother, Luke Reid. His father was either the late, Dr. Charlie Harris or the late, Dr. Joel Goran. But Charlie and Alex decided not to do a paternity test upon Charlie's request as he didn't want to know. Therefore, Charlie was his father in every way.

Joel was killed in a bomb explosion in Season 3, Episode 18 and Charlie died in the series final after being pronounced brain dead after a car accident.

Luke also underwent surgery after the car accident but made a full recovery.
