 The U.S. version of the last episode of the first series, called "Day of  Destiny" was originally two episodes. The reason for this is because Sailors  Mars, Jupiter, Venus, and Mercury die in the Japanese version, and it is  clear they are dead. In the DIC version, they make it seem that they have  only disappeared (e.g., when Mars is in that little ice hut on the ground,  they cut it off).
