[Aren't you coming with me?]
[What? There might be a world crisis? In three years?]
[Hahaha, then I'll come back and deal with it once I'm stronger.]
"Good grief, deal with it my ass. I'm still the one who had to come over and make good on your promise."
Here, Shen Qi noticed that the world crisis Mime Jr. had warned about would happen in three years.
Native Shen Qi had died a month or two after entering Ruins Valley. Shen Qi had transmigrated into this world another three years after that, while the first meteorite-the Giant Meteorite that Ruby, Sapphire, and Zinnia had dealt with together in the game's story-had arrived six months before Shen Qi transmigrated.
In that case, the world crisis Mime Jr. had mentioned was the huge meteorite Zinnia had been guarding against, wrapped in special energy that made it undetectable by existing technology.
At the same size, an undetectable meteorite was indeed more dangerous. After all, by the time it was discovered, it would probably already be visible to the naked eye, with disaster imminent.
When Shen Qi reached the Sky Pillar, Mime Jr. had indeed been there, and that was also where he had accepted the emotional script. This conclusively established that the divination Mime Jr. had performed all those years ago referred to the huge meteorite wrapped in special energy.
It was also because Mime Jr. could predict the huge meteorite that Shen Qi had triggered the emotional script when he followed Rayquaza into space to dismantle it. He had not strayed beyond the scope of his connection to the Pokémon associated with the script.
Everything made sense now...
"But where did Mime Jr. get the ability to prophesy and tell fortunes?"
In the end, Mime Jr. had not followed Native Shen Qi
