POST SCRIPT: There's a video out on the webs, I'm sure you could find it at YouTube or such, that began life as a psychological experiment. Some of you will have seen it in your professional lives, because business development/efficiency consultants tend to use it to make one of their key points. I think the video was made at Stanford or Berkeley, some place like that. It has a half-dozen college kids tossing two or three basketballs back and forth in a room. Lasts about two minutes. Before the video starts, you're told by the moderator that you should carefully count every time a basketball is tossed from one person to another. Your observational skills are being tested. Because there are 2 or 3 balls, it will be a bit challenging to notice every one, so watch closely. So the video starts, and you start counting. About the time you get to 10 or 15, a person in a huge gorilla suit walks into the side of the frame. He stands there a little while, then walks right through the middle of the people throwing the balls and stands on the other side a little while, then eventually wanders off screen at the opposite side. He was visible for over half of the 2-minute video. Here's the cool part: over half of the people who watch that video are so focused on counting ball tosses that they never see the gorilla, and are shocked to find out it was there. True story, go look it up.
How does that apply to our Lore Quandry? Just this way: the narrator of the story (either a hobbit with a quill pen in hand or a guy named Tolkien, depending on your preference) was probably too busy following the movements of his subjects, the Fellowship of the Ring, to notice even awesomesauce people like us showing up nearby from time to time. It's just human nature. It can be forgiven, and we can enjoy the opportunity it presents.
