Day 15: 3D

All my puzzles so far have been two-dimensional. Where is that third D? I have heard that it grins in scorn at those who attempt to escape it. So I went looking, and here's what I found:

I guess I did find a third D in all these places. But maybe I should have kept better track of where it was.

Hints: Each pair of sentences clues two different words. The two words in the pair should be the same length. And one of those words should contain three Ds. You only care about the location of the third D. The answer to this puzzle is a real word, but it's one you probably have never heard or said or read before. Sorry.
