[idea loosely based from an old piece I created a long time ago]
So, after the last time where Sonia trained Hop on how to deal with Koffling's gas. This time she decide to enact her special training on his pokemon, Intellion. By having him in a pokeball while she's preparing for the 'ideal' atmosphere for his resistance training.
And as you can see in the alt, It went as well as expected...
