They bump into someone

The four continued their trek down to the Pokemon Center, before they came across someone. Someone familiar to Ash.

"Hey, Viola," Ash called to the Santalune City Gym Leader from Kalos. She was snapping a photo of a wild Butterfree.

"Ash!" she said. "What a pleasant surprise! I forgot you lived in Kanto!"

"What are you doing here?" Ash asked.

"Well, there's a photography contest in Lumiose. They wanted us to go to different regions to get pictures of the local Pokemon. You wouldn't happen to know where any rare Kantonian Pokemon live, would you?"

Ash thought quickly and paused Delia, Jenny, and Misty. "Actually, I do."

He planned to make each woman act like a different Pokemon, then have Viola treat them like their respective Pokemon.
