Continuity mistake: As the nurse hits the ground, agent Ames runs out into the rain and stands in it unprotected. A moment later he runs around a corner and his coat is clearly completely drenched, as well as his hair and face. Ames then makes a jump up a wall and climbs up on the roof. As he pulls himself up onto the roof, both he and his clothes are completely dry.
Continuity mistake: When Gordie is crushing cans, the can changes to one of a different colour between shots.
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".
Answer: Max's disease is specifically tailored to work only on cells exhibiting Logan's genome. No one else would notice it.
