No prob, I'll be clearer. Phenomena may be indicated which, in form of episodes, very defined events, may be part of a "past", but the direction, inclination, patterns behind those events may still be lurking much later. (For instance, an expression of fascism ended in the forties, yet fascism may linger, emerge etc.) So, thin latency and occasionalities aside - minor traits and occurrences that just confirm exceptionality -, for the phenomenon to be over it must be uprooted. Unexpressed but latent is "not over": it remains of concern, it may express differently, it may re-explode.
