Pic related is a reference that Sabrina will meet GSC/HGSS protag in 3 years. But it is already established that RED and BLUE exist in LGPE world, with their achievements retconned into LGPE player character.

Would that mean in Lets Go Johto you will face LGPE player character instead of RED/BLUE? This is just an endless cycle of retcons that does nothing but provide cheap fanservice.

I would rather travel in a truly post HGSS Kanto where Red is the national hero rather than rehashing TR takeover Silph Co for the 20x times
