Puzzle #165: Blind Spot

Today the second puzzle that wasn't used in the WPC. This is a Blind Spot puzzle. It's actually a size smaller than the puzzle used at the WPC, which was 7x7. But I actually think this was the harder of the two puzzles. That's why the larger puzzle was used in the WPC. I like writing these puzzles, but I think they can be tricky to solve as the logic is a bit unfamiliar compared to other Latin square type puzzles.
