Am I the only one who's annoyed with the way people use the word "filler"? As Inigo Montoya said in The Princess Bride, "You keep using that word. I do not think it means what you think it means." A true filler involves a random location, a random Pokemon, no game references, no character development, no evolutions, etc. In other words, it could basically take place anywhere at any time. An episode that takes place in a location from the games and/or is based on an event from the games is not a filler.
