Oh Lord, what's up with Mr Period?
The flowers outside of Ash's house interest me a lot. It made sense if it was just a staff member saying goodbye, and it was only in XYZ47. But now that they're sticking around, well, I just don't know. It's quite odd, honestly. I can't wait until we get more previews, whenever that may be. There's a few directions they could take with this movie. Either it's a straight remake of the early episodes, which seems to be the most obvious, it's essentially an "Ash's last 20 years in review," which could be fun, or it's the first episode with some weird twist. There is one final option, and I only say this because they did indeed remember the flowers, but not any other changes to Ash's house like his display of items from the Diamond and Pearl series that made an appearance in the first and last episodes of Best Wishes. Yes, I do know he collected all of them on his journey, but the flowers were planted on his journey in Kalos, so who knows. Maybe, just maybe, it's about Ash's early adventures if his role with Serena in childhood was expanded, and she lived in Kanto instead of only visiting.
