who is he
This is a difficult question...because it's about Unova, and Unova is different in BW than in B2W2!
I'll admit, in BW I felt...well, the region awed me. It was amazing, but I do agree that there was something about how it felt that made it seem like I was maybe not so much a tourist, but rather a serious newcomer who couldn't really move in. Unova was just another lengthy stop in my trip around the world. Don't get me wrong--I loved it! But it didn't feel as homely to me.
But then B2W2 happened, and I don't know why, but in the sequels I definitely felt right at home. Perhaps I was used to Unova at this point, or perhaps it was the new areas or the changes, but B2W2 Unova really felt like "home" to me.
