I always saw them as a couple...until I saw the show and realised that they wern't.
Does that make sense? Probably not.
I'd seen many pictures, drawings, and articles about Fraggle Rock. I knew all about the characters, the trashheaps, and the raddishes...and I assumed that Gobo and Red were a couple. When I saw the show, I was amazed at how little Red and Gobo interacted and that they wern't together.
Of course I have only seen 12 episodes from random series...but...they seemed more like rivals.
