Since every travel companion + paul got a shoutout from the new preview episode, I think all these character will come back at some point during this series. This series, based on the preview, seems to have an emphasis on nostalgia (unlike Kalos), so past character are probably coming back!
So Lugia is going to be like Imperialdramon in Digimon Adventure 02, and move them around the world really fast! Sounds like a plan!
I hope traditional boat trips will happen, too! Maybe that's how brock gets to sinnoh for the contest?
Since there is no description, and we have no information on the episodes before this, it could easily be Dawn and Brock's pokemon. Maybe they traveled to Sinnoh to compete, and there was a reunion in Episode 7?!
8 Episode titles already?! And the episodes seem to hint at heavy continuity?!?!?!
What a day to be alive! PM 2019 is going to be a lot of fun!
How deep will the continuity go? In my opinion, it will all hinge on what the special shows this Sunday. Will it show a lot of older stuff? If it does...
