Diantha

"Ash Ketchum!"

Ash saw the Champion of Kalos, Diantha, exiting the chateau.

"It's been a while, hasn't it?" Diantha asked. "I haven't seen you since the Champions Cup."

"Yeah, I guess," Ash said.

"Dad?" Lorelei said in a defensive tone. "Who's this?"

"Oh, this is Diantha, the Champion of Kalos."

"Oh!" Lorelei said. "I'm Lorelei Ketchum, this is my sister Delia."

Delia waved.

"You never told me you got married," Diantha told Ash. "Or had daughters. I guess Lorelei is taking on the League challenge?"

Ash nodded and chucked a Pokeball at Diantha, catching her.

He decided to make her role that of his loyal, submissive, doting housewife.
