Colin Baker recalled that he was confused by The Doctor's behaviour in this story - I was very confused by it, but I had a very different problem, especially in 'Mindwarp' because there was a point when I said to Eric Saward, the script editor, 'When I'm tying Peri to this rock and threatening to torture her, am I doing it for some subtle reason of my own, because I think I'm being watched or whatever, or because I've been affected by the mind probe, or is the Matrix lying?'. Those were the three alternatives as I saw it. He said 'I don't know, you'd better ask 'Philip Martin'', so I got in touch and gave him those three alternatives, he said 'I don't know, Eric wrote the trial stuff, all the Matrix stuff was added after, by Eric, you'd better ask him'. So I went to John Nathan-Turner, he said 'Oh, whichever you like'. This is the level of involvement at the time. Eric was going through his own problems at the time, disagreeing with John Nathan-Turner on all sorts of things. I felt that was all very sloppy, it was all cobbled together a bit. The stories were written independently, and the trial theme was put on top. I felt it was the Matrix lying, so I really was torturing Peri. But it was very difficult. You expect the writers to know what's happening, but that's not always the case.
