He changes their age

"Ken, please, let's not get into a fight".

"It's okay, Audrey, I can take care of this".

Jack smiled. This brief conversation had given him an idea.

"Ken, Ken...your girlfriend seems more mature than you. Maybe it's time it becomes more obvious".

"What do you...ooooh..."

Ken's face suddenly became pale. He staggered, holding his girlfriend more tightly in order not to lose his balance.

"Ken? What's wrong?"

"I don't know, I feel like....nnnnng..."

"Oh my God, Ken, your face !"

Audrey's boyfriend reached for his face and gasped. His beard was gone, his skin felt...smooth..."

"What's happening to me?"

"You're younger. Much younger."

"Audrey...you're changing too !"

Ken was right. Audrey was undergoing the exact opposite. Her face slowly covered in wrinkles. Her curves started to sag, despite her screams of protest."

"No ! No ! Anything but that !"

But soon, the changes were already kicking. Ken looked like a teenager and Audrey like a woman in her late fourties.

"Please, stammered Ken. I'm sorry if I offended you. Just change us back and leave us alone".

"Change you back? But we are far from done here. You can't be a couple, not with such an age difference. We'll have to find a new relationship between the two of you."
