Summary
to be added

Characters

 * Fifth Doctor
 * Adric

Continuity

 * The unidentified gap in which the Fifth Doctor travels only with Adric would appear to be at some point between Castrovalva and Four to Doomsday, bearing in mind the tight continuity between other stories in Season 19, while Nyssa and Tegan are presumably having a break from the TARDIS.
