YMMV: The Clone
- Fridge Logic: Since the main thing that the muriatic acid, trisodium phosphate and silica gel latch onto in order to create the clone was hamburger meat, doesn't this mean Chicago is under siege from what is basically a giant killer beef blob?
- Paranoia Fuel: The ending's warnings about all those hazardous chemicals still in the sewers and what they may yet create.
- Science Marches On: Thomas and Wilhelm's definition of "clone" is a little vague and uses an older if technically correct meaning, quoted above. The creature was sort of "cloned" from dead hamburger meat, and does sort of "clone" itself by turning its victims into more of its own tissue, however this is far and away from the more popular concept wherein a clone is understood to be just an exact duplicate of an individual.
