Like I said, I don't know. That's just how it works here.

There's also one more thing I should warn you about. Johto is home to a dangerous group of individuals known as Team Rocket. They mainly steal Pokémon, but their tactics can be very brutal at times, and have managed to cause widespread chaos in the past. You can occasionally spot them in their uniforms, which consist of a mainly black attire with a large red "R" printed on their shirts, but they're typically disguised as regular civilians. Be on your guard at all times.

[SPOILER: you're talking to a TR member right now.]
