the Great Intelligence manipulating events to an end (in much the same way the Evil Guide does in Mostly Harmless).
Well, there was a Hooloovoo mentioned... though now that I think about it he might have said "Hoovaloo," which sounds more like a portajohn with a vacuum attachment. I don't care enough to go back and listen. Also, that guy wasn't even blue, unless he's just a lot of blue under the spacesuit.
Come to think of it, "hyper-intelligent shade of the color blue" also applies to Dr. Manhattan. But madness is seeing patterns everywhere.
Speaking of patterns, this one is the second time in a row that the introduction of a new companion has been followed by a variant of
The Ones Who Walk Away From Omelas. I don't know if I'd call twice a pattern, and really, I can't fault it, regardless. That's a very quintessentially Doctor Who-ish sort of story, and assuming that we're talking about a new viewer probably the most important thing to establish right after the two-hearts-timetraveler-blue-box stuff, which is actually called out explicitly in the dialogue. My only complaint is "yup, we have to do one of these" and "planet-sized Jack O'Lantern" really doesn't fill one with awe or fear like they apparently expected.
So whatever happened with gandpa mummy, or the little girl, for that matter? Who gives a fuck. Submarine story next week. Do you think they'll have a bit where everyone has to talk really quiet aboard a sneaky ship? Because it'd actually be justified for once there.
Also, there needs to be one throwaway along the lines of "Shit, where did I leave that swank leather jacket I wore two hundred years ago? That'd be really appropriate at this moment."
