If you want to know more about Castrovalva and its depiction of recursion, you should use the TARDIS’ databank to find out about it. All you need to do is to find the Index File by looking up the Index File in the Index File first… :D
I love the early Pertwee stories.
Not the reference I was making, but I get it. My joke was based on the Endless Eight from Suzumiya Haruhi (more specifically, the Trope page’s reference to it).
I’m only just about to watch Inferno, by the way. I saw Castrovalva a few years ago, but now I’m watching Classic Who in its proper order.
Someone’s manipulating Castrovalva! We’re caught in a time-space trap!
