Anyones here thought that there'll be more details of fossils in this ep? Since this ep is about two guys that have Obsessive Compulsive Disorder with fossils! They are lack of screentime and all the previous fossils eps did not give out a detail information about fossils and some of them just included the fossils Pokémon with no explanation at all! I think this is possible that Byron/Roark/underground man will explain many detailed information about fossils to Ash and co. There may even include some digging with fossils! I also think that it'll be possible that Roark and Byron will dig out some fossils extemporarily, revived them and used them to battle. Since they are arguing about who likes fossils more, they should have more than one fossil Pokémon. They really need to have some anime-exclusive Pokémon, it'll be too dull for all the Gym Leaders to have the exact line-up as in the games. After this ep, I hope Ash and co. will understand more about fossil Pokémon instead of merely consider them as mysterious Pokémon.
