Ignoring Puddle, Diyem stomped over to take a closer look at the lumps. "What are you talking about?"
"I'm Xerneas, or... I think I am. I know what an egg is when I see one." He pointed at the hoof. "That is an unfertilized egg. I'm sure you've taken lessons on that sort of thing." He looked at Nate, frowning--or perhaps it was a frown. Hard to tell with a head like that. "What happens when a female part and a male part go together?"
"...No," Diyem said slowly, eyes narrowed. "This is a prank. What are you talking about?"
"These are Eternatus eggs," Xerneas said matter-of-factly. "But something is... twisted about them. I don't think they're supposed to normally look that way. Something... dark about it. A twisted, corrupted aura..." Xerneas paused, glancing at Diyem. "A lot like you, actually."
Diyem was frozen, his face permanently incredulous and panicked. "How would such eggs be... activated?"
Xerneas looked at the egg, then at Rocky. He reached out and pressed his forehead against Rocky's Core, "Hmm..."
"Um, Diyem?" Owen asked, hesitantly stepping forward. "What's... going on? Eggs? I thought those lumps were just... I don't know, some kind of artifact from the meteor that can hold energy, like the Joulettes..."
"Joulettes?" Xerneas asked, eyes still closed.
"Yeah, um, shards of Joule that were corrupted by Shadows. It required someone from us pushing it in, though. And we were only able to do it once, for some reason..."
"Only once," repeated Xerneas thoughtfully. "That means you passed something from yourself into the egg. Because it feels, to me, that what is inside Rocky's egg... is some dark energy, some life energy, and some of Nate's energy. That dark energy... yes, I believe it matches you, Diyem. The life energy... I believe it is Joule..."
SPLAT!
Cal landed just outside the office--Owen must have told her the news--and rolled the rest of herself inside. Her head, mushed into the rest of her form, shouted, "What do you mean, I'm an egg?!"
Diyem's legs wobbled; Zinc, nearby, helped sit him down.
"I'm a father," Diyem said dumbly, staring blankly ahead.
