When we think of "coming on the scene," we might picture something or someone entering or appearing in a particular space or situation. However, there are a variety of antonyms that could be used to convey the opposite meaning. Instead of "coming on the scene," one could use phrases such as "leaving the premises," "disappearing from view," "exiting the stage," or "vanishing from sight." These antonyms suggest a departure from a certain place or situation, rather than an arrival or appearance. Depending on the context, using these opposite phrases could add depth and nuance to our language and communication.
