I've seen stories that the ones who went for Kanto and Johto are getting their shit kicked in by Rockets, and it's heartening to see those jerks receiving an appropriate welcome from Sinnoh, as well.
Though, I do have to be a bit pedantic: if she had somehow, miraculously, found you without any protection, surveillance, or general awareness of your immediate surroundings, after for some reason you never told anyone where you're going, it's not terribly difficult to hide a person in a snake. Once the shouting dies down, it looks like the snake simply recently caught a large-ish Lopunny, or a Blaziken if they're particularly brave.
