Have you ever been watching one of your favorite TV shows when it suddenly occurs to you that you haven’t seen a particular character in a while? Then, upon looking further into it, you come to find out they’re just gone? Once in a while, the higher-ups behind a show will come to the decision that a certain character is no longer necessary and elect to do away with them. Sometimes though, they’ll decide that it’s not even worth the effort of actually writing them off and the character is just ripped from existence. No explanation. No acknowledgment that they were ever there. They are simply no more.
