Small question before I make a fool of myself when I post, the people non-native to Kanto, is it being treated as them being dropped off in the starter town to meet with Oak and Yume? Or would they arrive in a close by town/city and have to walk to Palette town to get to the Lab? Also sorry if this was already addressed and I just missed it.
No worries. It wasn't addressed before, so good question.
For those folks who are non-native to Kanto, they could arrive by any number of ways such as by boat to any port city, plane to ANY city, or via some kind of Pokemon carrier service with flying types large enough and strong enough to carry their weight.
Eventually they'll have made their way to Pallet to meet Professor Oak and Yume and then they'll start.
