Everyone was getting pretty worried about Ness suddenly collapsing back in the Chaos Vortex, and no one knew what was wrong. They'd gotten the psychic to Dr. Mario's station to see if he could find anything the matter, but Mario's lab-coat clad clone didn't find anything of the sort.
"Guys, I-I'm getting a little worried," Lucas admitted, putting his hand on Ness' own. The psychic's pulse was incredibly weak. "What if Ness doesn't make it? The World of Trophies could collapse!" Then to himself he added, "With all of us in it."
Suddenly the little boy felt a hand on his shoulder. Pit smiled down on him. "Don't fret, Lucas," he tried to reassure the blond psychic, who attempted to blink away tears. "Trust me on this: Ness is going to be just fine, I'm sure of it."
Lucas sniffled. "I-I sure hope you're right..." he stammered with a quivering voice. He sounded so full of worry, he sounded like he was going to faint. Pit nodded, as if to say, "Of course he'll be okay."
Eventually, Dr. Mario came out of his clinic with a clipboard in his hand. "Here's your problem: Ness has caught a case of the Chaos Pox," he explained, tapping his pen on the symptoms: pale skin tone as if suffering from blood loss; horrible whooping cough; and sudden loss of consciousness. Lucas gasped, knowing that any illness with 'pox' in its name had to be bad.
"W-what does Chaos Pox do?" the blond psychic asked uneasily, holding his hands together as if in prayer.
"Well, nobody's exactly sure if there're any negative effects, or any positive ones, but you'll need to keep Ness safe in order for the disease to die down," Dr. Mario explained. "As for how one gets the illness...in short, it basically afflicts anyone not used to how that...moth thing...dies. If one inhales its ashes, there's a chance, albeit slim, they'll come down with Chaos Pox, and it is extremely rare. In fact, one's odds of catching the infection after the Chaos Kin has been killed are about 1/8192."
"Not quite as common as finding a Shiny Pokémon," Kaelynne realized, "but the exact same odds as in generations one through five; in short, the odds of finding a Shiny from Kanto to Unova."
Everyone started giving Kaelynne a death glare (of death) that spoke, "What the Arceus?"
Dr. Mario handed the clipboard to Pit, then explained that he'd have to watch out for any of the listed symptoms, or Ness, as Lucas had feared, just might not make it.
