So, I was listening to episode 66 of the
It's Super Effective podcast, and they were talking about Mistralton City. It hit me at the point where SBJ was saying that they didn't do anything with the planes, and he and David said "Not yet."
Then it hit me.
What if in Pokemon Grey, we're getting Hoenn along with it? It'd be hard to go back and redo the R/S games without Kanto, since they canonically take place at the same time. Why not just throw it in this way?
What really convinces me though is when you beat the Pokemon League (I think it's a bit late to worry about spoilers anymore), Looker said that there were reports of N in Hoenn flying on some Dragon Pokemon. So, you go to Hoenn to find out what happened to him, and at the same time, take place in the League.
And you get to Hoenn via Mistralton's Airport! They had to have had a reason for including that, you know? Thoughts?
