[[WMG: Doctor Petrov failing to account for TheMole is due to one of three possibilities]]
* During the film's climax, Captain Ramius orders the ''Red October'' [[AbandonShip evacuated]], he orders Doctor Petrov to get an accurate count, so that they do not accidentally leave any crewmembers aboard. Of course, it is later revealed that TheMole is still aboard, which could be due to three possibilities:
** The Doctor was incompetent, or at best, distracted, and goofed the count. He failed to realize that he had miscounted the sailors as they disembarked. (Judging from the novel's portrayal of Petrov, this is the most likely possibility.)
** TheMole was never included in the official crewcount, meaning that an accurate count would not have revealed him being missing anyway.
** Doctor Petrov was ''also'' a mole, and knowingly allowed TheMole to remain aboard because he suspected Ramius of being up to something.
