Partners in Danger Chapter 9: The Haunting of Mary Jane - S4-E9
Plot hole: Miranda Wilson states that after the accident on the movie set left her face disfigured, she hid in the catacombs by the bridge and almost died from her condition until Quentin Beck found her after he was released from prison. Beck is the one that caused the accident in the first place, so even if he only spent a month in prison, Miranda Wilson would have died from starvation or malnutrition - if not infection from her untreated facial disfigurement - long before Beck could have been released from prison and found her.
Partners in Danger Chapter 10: Lizard King - S4-E10
Plot hole: When Debra and Margaret arrive at the underground arena with the device that can revert the humanoid lizards to their original forms, they lose control of the device and it ends up in the hands of Ghila, who monologues that the humanoid lizards' existence was an accident and that she will use the device to return them to being regular lizards. Ghila had never seen this device before, nor did anyone tell her what its purpose was, so there's no way she could have known it was designed to reverse the mutations.
