You had a five year old son with L. He was a smart kid, wanting to be a detective like his father. He was always trying to help with his dad’s cases, which L didn’t mind, although you hated. Both your son and L didn’t understand why though.
You came home late after a long day at work, going into the living room as you heard voices. You saw L with your son on his lap, talking about another case L was working on.
