Ep. 90: Showdown at the Gates of Warp!

90

Satoshi, Koharu, along with Satoshi's doppelganger reunite with Go and the two Hikaris. Professor Nanakamado directs the group to the Spear Pillar, where they would be able to find Dialga and Palkia. Satoshi, Go, Koharu and Hikari arrive at the Spear Pillar and find the two legendary Pokémon contained in the red chain, which is causing the distortions in time. The quartet plans to break the red chain. However, the alternate Rocket Dan prevents them from doing so. Rocket Dan reveals that they are the ones behind the scheme, and plan to catch Dialga and Palkia along with all of the rewound Pokémon and train them as their own. Suddenly, Dialga releases its power, causing Rocket Dan to be sent blasting off and all the Pokémon reverting into eggs. Satoshi and the others call for Arceus' help, which eventually frees Dialga and Palkia from the red chain, and the two legendaries return everything to normal. (Source: Wikipedia)
