In the seriesEdit
In Death Masks, young Harry Carpenter almost touches Lasciel's coin, which he is prevented from doing by Dresden, who picks it up himself.(reference needed) Amanda gives him the nickname "Bill", on the basis that there is already a "Harry" in the family.(reference needed)
In The Warrior, young Harry Carpenter welcomes Harry Dresden by climbing on him, and developing selective deafness when his mother protests Dresden is not a jungle gym. He then jumps on his father, who is rescued by Alicia, getting young Harry to have a bath.
In Skin Game, Harry Carpenter is in the middle of his adolescent growth spurt. He is going by Hank, possibly to differentiate him from his namesake. He is willing to play wild games with Maggie and his sisters, and later gives his father Amoracchius to give back to Dresden.
