Yet come the early Davison era, there was little of this happening for the characters. Adric only really came to the fore in Earthshock and Nyssa had Black Orchid. Tegan seemed to be the preferred companion for the writers, and had important roles in Castrovalva, Four to Doomsday and of course, Kinda. There wasn't the sharing of the action between the characters during this era, and even if the writers saw Tegan as the preferable option to write for, the script editor should have ensured that things were more equally weighted.
