It was announced that there will be three more episodes in Season 15. To this point everything is fine. But then it's said there will be 25 instead of 22 episodes although all seasons since 8 have 24 episodes.
That's why I'm confused. Three episodes more in season 15 would mean: 27 episodes. 25 episodes in season 15 would mean: 1 episode more. So what's right?
