Clint Barton

The line “Clint, son of Edith” in Avengers: Endgame is a Marvel Comics reference. In the comics, Clint Barton and his brother Barney were the sons of Harold and Edith Barton. The boys loved their mother but hated their father, who was a physically and verbally abusive alcoholic. Harold eventually killed both himself and Edith in a DUI car accident, after which Clint and Barney were sent to an orphanage.
