An assassination method is one of many different ways to kill a Sue, ranging from the classical arrow to the chest, to the more creative method of pitting them against another Sue with a similar description. This is an incomplete list of those methods, as listing all sorts of banal assassination methods (Pointy Objects, guns, pushing Sues off high places, etc.) is a waste of space and time—we'd have to list every time an agent broke a Sue's neck. They are classified by the continuum in which they took place, usually but not always the continuum of the badfic. Assassination methods which are closely in line with what could happen in canon tend to be more effective at getting the continuum to revert to its normal state.
