Originally the episode was to end with a scene where the Doctor and Jo went back to the lab, and saw their earlier selves working at the TARDIS console. However, the last episode was overrunning and director Paul Bernard
decided to cut the scene, which he personally disliked. Terrance Dicks
tried to persuade Bernard to put it back in, but Bernard refused and Barry Letts
agreed that it should be cut. Dicks would later restore the scene in his novelisation of the story. See more
