Day 260: Doctor Who and the Silurians Episode 3

There's an interesting character in this story, Dr Quinn. He appears to be in league with the titular Silurians and, as a result of the prospective length of this story, one can easily expect that his story will develop over the course of the following episodes. We expect that the Doctor will find himself fighting against him, or perhaps ally himself with him. At the very least, he is set to be a major character over the course of the story, in much the same way that Tobias Vaughn was in The Invasion. However, he is dead at the end of this episode. This is a fantastic development because it clearly indicates a shift in the tone of the story, from one plotline to another (as yet unknown) plotline. Also, it indicates that Malcolm Hulke, the writer, is keenly aware of how stories normally develop and is making a conscious decision to not go along that pathway, indicating him as one of the more interesting Doctor Who writers.
