We haven't talked about this writer in a while, but it's almost hard to talk about Doctor Who without him -- Terry Nation, the inventor and most prolific writer of the Daleks. We've done all of those, of course, but he also wrote two stories with no Daleks in them whatsoever: from season 1, "The Keys of Marinus," and from season 13, "The Android Invasion." Nation fell into certain traps and narrative tricks when he wrote Daleks; did the same happen without the trundling war machines? Kyle and Erik find out!
