>>54787430There literally isn't anything to discuss about any other theory. The game goes out of it's way to make everything that could be assumed to be the result of time travel be of questionable authenticity (Paradox Pokemon are actually from occult magazines, the "time machine" just makes shit appear in Pokeballs instead and is never used in any provable way to actually travel through time, and all theming around Tera crystals effectively ignores the concept of time travel but heavily revolves around dreams and wishes).
Look at the first DLC and how Ogerpons unique interaction with Terastallization is specifically described to be it's overwhelming desires and memories. They literally could not be making this theming more obvious. Meanwhile the closest thing you could possibly even TRY to argue as being time travel in that DLC is that some people see dead family member at the Crystal Pool but even that makes more sense with the "dreams and wishes" theory.
Hell, the thing they could have actually very easily attributed to time travel, the fucking Blood Moon Ursaluna, EXPLICITLY HAS NOTHING TO DO WITH THE TERASTAL PHENOMENON.
