BW083: Crisis at Ferroseed Research!

Episode Plot
After hearing the news that the Opelucid Gym is closed, and the advice given by Mr. Hattori's butler, Ash and co. decide to head to Virbank City for Ash's final Gym Challenge. On the way they encounter Iris' rival Georgia and her Vanilluxe who has a personality of making friends with a Dragon-type Pokemon like Axew. She's on her way to Ferroseed Research looking for moss that powers up the Pokémon's skills created from the thorns of a Ferroseed. However, as Ash and co. take a tour around their research with a lab research assistant Case who's being a tour guide, the chargestones those Ferroseeds absorbs (that came from Chargestone Cave), releases much more moss and grows out of control and covers the whole building, and spreading everything in its path. Not only that, their spores that any Ground or Electric-type Pokemons inhaled it would make them sick. And with Iris trapped on the roof with Axew, Ash's Oshawott and Georgia's Vanilluxe, how will she get out of this one?

Trivia

 * As of this point, all the members of the Vanillite evolution family have appeared under the ownership of a rival trainer: Trip has a Vanillite, Brycen has a Vanillish and Georgia now has a Vanilluxe.
 * This is the second episode in a row when main characters meet their rivals again to the other. First, was Burgundy in the last episode and now they met Georgia.
 * The chargestones from Chargestone Cave those researchers got makes its third appearance since BW064: Crisis at Chargestone Cave! when Team Rocket forced all of those Joltiks and Galvantulas off so they could steal them all for Dr. Zager to power up his fossil restoration machine. With the computer data they've stole from Prof. Juniper and Dr. Fennel in BW039: Archeops In The Modern World! in order to restore Tirtouga from a Cover Fossil in Twist Mountain in BW077: A Restoration Confrontation! (Part 1) and 2 to use its life energy to keep the expanded space-time warp called the "Time Gate" open, so they can capture all of the Ancient Pokemons from the past.
