Yeah, poor Adric; you can sort of tell when I'm none-too-confident writing a particular character, because I start making them broader and a bit exaggerated, and I'm maybe a bit guilty of that with Adric. I do think the Four and Romana and K-9 and Adric thing worked well for the couple of stories it lasted, as did just Four and Adric together in Keeper of Traken, but I think you're right; it wasn't as good with Five.
