( I'm still thinking about that spec offa OG re: the recent SJA nemesis... )
However, I'm thinking of it now in conjunction with something I remember in "The Sound of Drums" which, at the time, didn't make a whole lot of sense (and still doesn't, not really)...
Toclafane: "We have to escape! Because it's coming, sir! The darkness! The never-ending darkness. The terrible, terrible cold. We have to run and run and run and run!"
At the time, I just figured they were the "Utopia" humans still reacting to the encroaching end of the universe, despite not being human anymore. However... I had wondered if it may have a bigger meaning than that or at least double entendre. What were the Toclafane (and, possibly, the Master through them, something he might have unconsciously programmed in them) so afraid of? ( Tying SJA thoughts to this. )( Then I thought of something nemesis said in SJA which, granted, is pretty much standard baddie dialogue of just about any baddie ever, but... )
Maybe Rusty has had a grand plan all along? And it's been spilling out all over the place. Bad Wolf? The release of Abaddon? ( That other bloke from TW? This guy from SJA? )( And it's all been leading up to... )
**Also, there are "Doctor Who" spoilers (or huge rumors which are hardly spoilers, but I'll call them spoilers to be on the safe side) in the comments.**
