The Fifth Doctor, Nyssa, Tegan, and Turlough

This is an interesting section designed to make use of a TARDIS team that didn’t really get much time together on TV. There seems to be a general agreement not to set stories in the period where Turlough is controlled by the Black Guardian (except for one Short Trip), so in order to get Nyssa back on the team, she needs to return after her departure. It feels a little awkward, but Tegan already did it, and they handle it as best they can. This is another long stretch of stories where the release order mostly matches up with chronological order for the characters.
