We barely got to know Charles before he was fatally shot by the gunman, but that didn't make it any less painful. His dying wish for Bailey to tell Reed that he loved her was the worst because 1) Reed didn't love him back and 2) Reed was already long dead by then.
Charles returned for the Season 8 "alternate universe" episode, in which he muttered, "Shoot me now." Get it?
