My true disdain for this show is that they incessantly drop the ball on providing any meaning for anything. For example, the scene with Blackie and Blondie - when Blondie keeps telling Blackie to leave her to die - we get a sullen and quiet Blackie who decides to not let her die because of, well, whatever. They needed to have Blackie reference something along the lines of how she wont leave Blondie to die because there is so little life left in the world and that life is to be cherished and yadda yadda. But the writers never do anything like this. The characters are so different from normal people that they might as well be extra-terrestrials
