AN: I just have to yell at Ash for all of his stupidity. Also my Pokemon spelling skills and information is iffy, so no need to point it out.
Ash, Serena, Clemont, and Bonnie were hanging around a fountain in the center of a town on a lovely day. For some reason they were practically the only ones there. Unexpectedly, a young stranger walked up to them. She got right up in Ash's face, making him flustered. Serena felt a faint flash of jealousy.
"When we're you planning on telling them!?" She sounded furious and exasperated.
"Tell them what?" He was genuinely confused.
"Oh, I don't know, how about everything? First day out with Pikachu, he sees Ho-oh. From then on, he's met Articuno, Lugia, Zapdos, Resheram, Palkia, Zekrom, Jirrachi, he's best buds with Giratina, and he's traveled back in time to save a town from the wrath of Arceus himself, just to start the list."
Serena and Clemot were bewildered at all of this new information, while Bonnie's eyes had lit up in wonderment.
"Wow, Ash, you really know all of those legendary Pokemon? Can you introduce me?"
Ash was getting uncomfortable at how much this stranger knew.
"Y-yeah, it's all true, b-but how do you even know all this?"
The stranger grinned.
"Oh, I've met some of your past comrades. I must say, you attract quite a lot of attention." She then pulled out her phone, showing Serena their pictures one by one.
"Misty. May. Dawn. Iris. Oh, and here's a picture of his Bayleaf that has some sort of obsession with him!"
With each name, Serena became more and more irked. A dark purple aura grew behind her. Clemot had 'conveniently' slipped away some time ago.
"Ash, why didn't you tell us." Her words were slow and dangerous, each laced with venom. She said 'us' but everyone knew she meant 'me'.
"I-um-well-uh-you see-um..." Ash tried in vain to stutter out some semblance of an explanation, not really sure of the reason himself. Before he could voice this utterly ingenious thought, he found himself being chased by a demon woman weilding a stick found on the ground, the sweet Serena nowhere to be seen.
The stranger and Bonnie laughed, confident that he would not be killed.
"Looks like someone has a Yandere streak."
It was a beautiful, sunny day where lots of new knowledge came to light.
