In episode 12, behind Ben's desk, there's an image of the planet Saturn in the art on the wall. In the red room in the first episode of season 3, there's an art deco sculpture of the planet Saturn on the end table next to Dale's chair. In season two we're told that the door to the black lodge opens when Jupiter and Saturn are conjoined.

Related maybe, in Greek myth, Saturn (who is modernized as "Father Time") is a tall old man who eats his children, like the Giant but in reverse?
