Who says it has to be an LDR, an LTR or an R at all? As of 2056, it's "hey, free kisses" on the couch (overdue for burning, I agree) with the comic relief trapped in the kitchen. As long as Marten keeps his head, it can be "We both agreed that was fun and nice, now have a nice life at your end of the country" with maybe "we'll be glad to see each other approaching on the sidewalk someday" in the future.
Oh, "comic relief" is unkind, I suppose. At least as far as Hanners, the one character in the comic who unfailingly and (almost) unflinchingly demonstrates she gives a damn about the other person in any of her interactions.
