Character mistake: When Olivia and Dr Galina are in the bathroom, Galina mentions an umbilical chord, from a baby whose mother died (Nadia), that contained Olivia's mitochondrial DNA. Mitochondrial DNA comes from the mother, so Nadia's Mitochondrial DNA came from Letha who got hers from Marie, absolutely nothing to do with Olivia.
Continuity mistake: Peter and Roman dig up Lisa's corpse to steal internal organs. When they cut her open blood and fluids gush from the wound. A vehicle approaches, forcing the two to flee the scene. The Sheriff and Dr. Chasseur, who arrived in the vehicle, view Lisa's corpse a few seconds later and there is no blood on or around the body.
Factual error: The show is supposed to be set in Pennsylvania. But when Roman is getting treatment in a doctor's office, and his phone vibrates on a table next to him, a close up shot of his phone is shown and the cell service is ROGERS. This cell service is only in Canada. (00:22:00)
What Peter Can Live Without - S1-E9
Continuity mistake: Right after the opening credits Dr. Chasseur is in a hotel room. The U.S. Marine Corps tattoo on her shoulder is missing most of the time. (00:07:30 - 00:11:30)
