I've just watched the Keeper of Traken followed by Logopolis. Traken was great - one of my favourites, great story, very good supporting characters, great interior shots and realistic outdoor shots (I know the trees aren't real!), the Master is great and has a reason for being in the story and Nyssa starts her run. But then we get Logopolis and Nyssa begins as a companion. How did she get to Logopolis ? The Watcher took her there - really ? By magic I assume. I love Nyssa as a companion - but the explanation for her beginning as a companion has to be one of the worst ?
What does everyone else think ? Were there other badly introduced companions ? I think Dodo is probably one of them !
