He's traveled the world to understand what he's gotten himself into, and now that he has a firm grasp (20-40 years later) he's returned to Sinnoh to try again, by capturing Arceus. He forms a stable timeloop with the original DPPt games because the family crest the Galactic symbol is based on is the one he creates in PLA.
