Factual error: A major plot point for this season is that Max's genome has no "junk DNA." Instead, it's all coded for something. A standard human genome has about 95% junk DNA, with the remaining 5% coded for building proteins. However, research from the 1980s and 1990s indicates that junk DNA isn't junk at all, but rather explicit instructions to the cell on when and how to read the protein-building instructions. If Max doesn't have that, then her cells would never be able to build proteins and she would never have been born. Even though Max has extra coded DNA for an unknown purpose, there is still no way she could live without "junk DNA".

Continuity: When Gordie is crushing cans, the can changes to one of a different colour between shots.
