Also, is the implication that Paraguay guy (Paraguy? lol) is driving to the US to meet Carol? How is he going to get past the Darien Gap? That's not a detail Gilligan would miss.
He could just ask them to bring him there. He also could conceivably have a boat.
Boat is more likely. He so far, has been very hesitant to have any interaction with the hive. For all we know he may not even know what's really going on.
And as someone pointed out, considering the title of the next episode, it's very possible he runs into the issue of driving to the US from South America.
My guess is he gets to Turbo, Colombia, hit's the dead end and the hive is there with a boat or a plane to take him the rest of the way. Whether he accepts, who knows.
