Pokémon: Arceus and the Jewel of Life/Headscratchers


 * To go along with the Grandfather Paradox entry,
 * As well as if it was returned to him, and everyone returned to the present, Arceus would not have continued fighting until he recognized Ash. In fact, everything past the Ninth movie (The Darkrai and Shaymin movies) would have been un-written.
 * Wait... Dawn acquired an item during the tenth movie that, if I recall correctly is eventually talked about and used in the anime. Wouldn't this essentially unwrite pretty much from D&P's midpoint onwards?
 * It might be the fact that Arceus himself was present at the time, remember, he is a God. Perhaps returning to the present saved them and the past Arceus delayed the time rewriting until after they were safely in the present?
