after some thought, I feel the best way to salvage the Ray/Jenna/Charlie situation would have been to keep them on the show for another 2 or 3 seasons, following their lives in “Switzerland”, which would consist of stock establishing shots of the Alps, fake studio sets, and obvious California landscapes, with locals played by American actors with terrible ‘Swiss’ accents.
Ray would have a hard time interacting with the ‘locals’, who’d be unable to understand his clumsy quasi-Germanic adaptations of down-home American cowboy jargon. Jenna and Charlie would fare better, making friends and enjoying the sophisticated culture, with Charlie dating a series of seemingly polite Swiss teenagers. Baby Lucas would be so baffled that he’d attempt to crawl back to the USA, a saga detailed in a special two-part episode.
