In Part 4 of the I, Davros storyline, the switch flips. Davros changes from being a scientist who wants to seek the truth to being a zealot driven to completely exterminate the Thals with his new species. But Davros is not above making use of the Thals themselves to further his aims: a Thal spy uses a voice synthesizer to get around voice-recognition locks, and this ends up being useful to the Daleks. This same spy also involuntarily donates his brain to science. And this is where we find out how the Daleks got their name: from the language of the Dals, an ancient Skaro civilization. Daelek means, basically, godlike. So no shortage of ego for these ones.

This was such a good conclusion. Chilling, especially that very last line. The perfect ending. ( )

Guilt is the only true prequel of the four stories, in that it deliberately takes us just up to the point before Genesis of the Daleks, with Davros overcoming disability and captivity to join forces with Nyder (Peter Miles brilliantly reprising the role) and develop the elements which are to be united in the form of the Daleks. Even though the trajectory is pretty much pre-set, it is again an excellent ride. ( )
