- (時をかけるサトシ！ロトムの願い！) is the 31st episode of Pokémon the Series: XY Kalos Quest.

Synopsis
When the gang arrives at a hotel for the night, they witness the owner taking Pokémon from a trainer he defeated. When Ash stands up to battle the owner, he and his gang attempts to take him and his friends down, but a Rotom appears and saves them. It soon reveals that the owner is actually a current one, seeing that the original owner, who was the trainer of Rotom, was stolen by the current owner after Rotom chickened out of a battle for the hotel, so they decided to help by going back in time to prevent the incident from happening and return the hotel to it's original glory.
