These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Adaptation Displacement: The reason it's called "Retreaded" is because it's a remake of an earlier fic SiFi270 wrote, which has since been deleted. Now that the Retreaded version has also been deleted, the point is moot.
