What? You thought I'd have more to say? I'm just strapping myself in for the ride to the very end. It makes no sense to theorize at this point. Or even to criticize. Team Darlton are going where the story leads them, and it's always been their story to tell.
But of course, Toobworld Central does have some things to say - especially in tying the series to 'Doctor Who' with two separate incidents. And there may be other things to say, other theories, once we see how it all plays out.
