I think that's to balance out all of the other 'stuff' that Tom heaps on the readers like 'Well at least there's ONE couple with a relatively normal relationship!'

It's implied that most of their non-plot-related relationship is off-screen, anyway, since they're the most "normal" couple in the group.
