That seems plausible. The last five minutes could either be a montage of future shots – weddings/births/career achievements etc, or there could be something dramatic that sets up another season. I’d much prefer it if the last eps could be all about the future though. I thought Dawson’s Creek managed that pretty well in its last two eps. I guess DR won’t have that option if there’s the tiniest possibility LG will do another year. He has to keep the storyline open for as long as possible.
