Sky Trainers
This isn't really a glitch, the player can't speak with them because they're too far away, and when the player steps into the area, they're not programmed to do anything if the player's already fought them. Like the previous rebattling trainers, Pokémon Breeder in Black 2 and White 2. -EVsandIVsaurs 12:18, 31 October 2013 (UTC)
You can't rematch Sky Trainers, though, and Pokémon Breeders could be spoken to after battles. It seems odd that you addressed it as "it always happens", because it clearly doesn't. PokemonMasterJamal3 (talk) 12:26, 31 October 2013 (UTC)
