The episode starts with Ash and co. entering Cyllage city.
Ash is excited to take on the gym.
Ash rushes to go to the gym, but Serena tells him to stop and points out to him where the gym is.
Ash and co. are now inside the gym and Ash sees somebody climbing the big rock climbing wall in the center, it is the gym's leader, Grant.
Ash is now climbing the rock wall and eventually makes his way to the very top, where the battlefield and Grant are.
Serena and the others then makes it up to the top as well and start to watch Ash battle.
The referee shouts out the rules as Ash and Grant get ready.
Grant brings out a Pokeball, enlarges it and then releases his Onix out of it.
Ash then brings out his Froakie.
Serena remembers when Ash had a training battle with Froakie and Fletchling in the previous episode, well the Amaura one.
Ash and Grant begin their battle.
Onix uses Rock Polish and now Froakie is charging towards Onix.
Froakie uses Double Team and surrounds Onix.
Onix then uses Rock Tomb and Ash tells Froakie to dodge, which he does.
Froakie then jumps off the rocks in order to get closer to Onix's head.
Froakie fires a close range Water Pulse on Onix's head and Onix counters with Iron Tail, which Froakie dodges.
Froakie then gets close to Onix's head again and uses another close ranger Water Pulse, which knocks Onix out.
Ash wins that match.
Grant then sends out his Tyrunt.
Dare Da? Tyrunt.
Tyrunt lets out a big roar as it begins to fight against Froakie.
Ash uses his Pokedex on the Tyrunt.
Froakie uses Double Team again, to surround Tyrunt.
Tyrunt then also uses Rock Tomb to counter Froakie's attack, but Froakie quickly dodges.
Tyrunt then lets out a big meteor like attack, that knocks Froakie out.
Fletchling then comes out and uses Razor Wind, but Tyrunt is hardly affected.
Tyrunt then makes quick work of Fletchling, so Ash then brings out Pikachu.
Tyrunt uses Draco Meteor and Crunch.
Pikachu uses Iron Tail and Tyrunt uses Dragon Tail.
Ash's Pikachu eventually defeats the Tyrunt and Ash wins his second gym battle and is presented with his next badge.
Ash and Pikachu do a victory pose, before Ash puts his badge in his badge case.
Ash and co. say goodbye to Grant as the sun sets and Ash is excited for something, probably his next gym battle.
To be continued.
