'So...if you beat me, I'll let you go...but if you lose against me, you'll put on this dress and become a child of SBC!' As you stared at your Pokémon knocked out by her Mega Clefable, those words began to sink in.

Jacinthe had been holding tournaments in Lumiose City for a while in order to make trainers the best they can possibly be. Once she sees a trainer she likes, she'll continuously stalk them mainly as a hologram until they fight in her tournament. You happened to be one of those- but while you were willing to battle, she also placed a bet on an outfit she had commissioned- stating it apparently involved a 'white garment that'll make you a child of SBC'. She didn't show it though- however, you knew you would win anyway...and it looks like that assumption was wrong.

'Alors, you seem to have lost against me. That brings up my part of the deal, correct?'
