Keith has been gathering up sick Pokémon and trying to get them to come back to the nearest town for some help. It goes as well as can be expected, with the larger Glalies being the most difficult to transport if they're too tired and worn out to float themselves. For the most part, he keeps his team put away to avoid them getting sick for now.

That said, some of them probably will anyway... maybe even Keith himself from staying outside too long. He's also a prime candidate for getting surprised by a Glalie sneeze. Ouch.

After the outbreak fades, Keith goes back to just trying to do normal things if he and his Pokémon aren't stuck recovering themselves... and that means hopefully just trying to act normal and not do anything special either in favor or against the Snorunts once they start their swarm. He's really trying not to end up with bad luck again.
