As circumstances keep throwing them together, Steven makes it clear to both his wife Claudia and Luke that his and Luke's relationship is purely platonic. Still, Claudia cannot ignore the warning signs, and Steven cannot ignore the attraction. He and Luke eventually begin a relationship, and Claudia finds solace with Steven's brother, Adam. Later, when the entire family (including Luke) travels to Moldavia for the wedding of Steven and Adam's sister Amanda, terrorists attack the chapel. Luke is shot in the head trying to protect Claudia from machine-gun fire. He later dies in Steven's arms.
