Nick Fury had a relation with Pamela Hawley, a British countess. During a rescue mission to bring back Percy Hawley known as Lord Ha-Ha, her brother and Nazi sympathizer, Junior was killed. Fury put the blame for Juniper's death on himself, thinking he did not push the Commandos enough. Fury decided to deepen their training until they become the toughest, most dangerous squad in the war. A few missions later, the British soldier, Percival Pinkerton, replaced Juniper in the team. Jonathan Juniper was the grand-uncle of S.H.I.E.L.D. agent Roger Juniper.
