Goofs

After landing in the TARDIS, the Doctor and Romana become separated when Romana climbs a hill to get a better reading with the tracer for the Key to Time. She's kidnapped by the local swamp tribe, and a bit later the Doctor is taken by workers from a methane refinery. While they are apprehending him, the tracer can clearly be seen sticking out of his coat pocket, even though Romana would have had no chance to give it back to him. See more »
