Nixie brought Leon and Parker with her to the farmer's market at the park, unfortunately Leon lost his pelenka and Nixie didn't have any spares on her, lucky for her Aria witnessed this and was more than happy to lend her one of Ennui's diapers. Leon liked how they felt and asked Ennui, who was eating an apple, to help him try and get his twin brother in one of them as he thought he would also like them.
