Ok kiddo, let me explain to you what double ep means.
Do you know what ep means? It's short for episode. An episode is like a part of a story, kind of like a chapter in a book or a scene in a movie.
So when we say "double ep" we mean that there are going to be two episodes instead of just one. This means we get to see more of the story and find out what happens next!
Sometimes TV shows will have a special event called a "double ep" where they show two episodes back-to-back, so you get twice as much story in one sitting. Pretty cool, huh?
So basically, a double ep just means double the fun and double the story!
